Title: Multiconfigurational quantum propagation with trajectory-guided
generalized coherent states
Authors: Adriano Grigolo, Thiago F. Viscondi and Marcus A. M. de Aguiar
Categories: quant-ph physics.chem-ph physics.class-ph physics.comp-ph
Comments: 29 pages, 3 figures
A generalized version of the coupled coherent states method for coherent
states of arbitrary Lie groups is developed. In contrast to the original
formulation, which is restricted to frozen-Gaussian basis sets, the extended
method is suitable for propagating quantum states of systems featuring
diversified physical properties, such as spin degrees of freedom or particle
indistinguishability. The approach is illustrated with systems of
bosons trapped in double- and triple-well potentials, most adequately
in terms of SU(2) and SU(3) bosonic coherent states, respectively.

In the present note we consider an example of a boundary value problem
for a
simple second order ordinary differential equation, which may exhibit a
boundary layer phenomenon. We show that usual central finite differences,

Title: Numerical solution of conservation laws on moving grids
Authors: Gayaz Khakimzyanov, Denys Dutykh (LAMA), Dimitrios Mitsotakis, Nina

In the present article we describe a few simple and efficient finite
type schemes on moving grids in one spatial dimension. The underlying finite
volume scheme is conservative and it is accurate up to the second order in
space. The main novelty consists in the motion of the grid. This new dynamic
aspect can be used to resolve better the areas with high solution gradients
any other special features. No interpolation procedure is employed, thus an
unnecessary solution smearing is avoided. Thus, our method enjoys excellent
conservation properties. The resulting grid is completely redistributed
according the choice of the so-called monitor function. Several more or less
universal choices of the monitor function are provided. Finally, the
performance of the proposed algorithm is illustrated on several examples
stemming from the simple linear advection to the simulation of complex
water waves.

Title: The Necessity of Quantizing Gravity
Authors: Jeremy Adelman
Categories: gr-qc physics.hist-ph
Comments: 13 pages, two figures
The Eppley Hannah thought experiment is often cited as justification for
attempts by theorists to develop a complete, consistent theory of quantum
gravity. A modification of the earlier "Heisenberg microscope" argument for
necessity of quantized light, the Eppley-Hannah thought experiment purports
show that purely classical gravitational waves would either not conserve
or else allow for violations of the uncertainty principle. However, several
subsequent papers have cast doubt as to the validity of the Eppley-Hannah
argument. In this paper, we attempt to resurrect the Eppley-Hannah thought
experiment by modifying the original argument in such a manner as to render
immune to the present criticisms levied against it.

Smectic liquid crystals are remarkable, beautiful examples of materials
microstructure, with ordered patterns of geometrically perfect ellipses and
hyperbolas. The solution of the complex problem of filling three-dimensional
space with domains of focal conics under constraining boundary conditions
yields a set of strict rules, which are similar to the compatibility
in a martensitic crystal. Here we present the rules giving compatible
conditions for the concentric circle domains found at two-dimensional
interfaces with planar boundary conditions. Using configurations generated
numerical simulations, we develop a clustering algorithm to decompose the
planar boundaries into domains. The interfaces between different domains

of our approach to describe the full three-dimensional smectic domains,
the variant symmetry group is the Weyl-Poincar\'e group of Lorentz boosts,
translations, rotations, and dilatations.

van der Waals (vdW) heterojunctions formed by two-dimensional (2D)
have attracted tremendous attention due to their excellent
properties and device applications. However, current 2D heterojunctions are
largely limited to atomic crystals, and hybrid organic/inorganic structures
rarely explored. Here, we fabricate hybrid 2D heterostructures with p-type
dioctylbenzothienobenzothiophene (C8-BTBT) and n-type MoS2. We find that
few-layer C8-BTBT molecular crystals can be grown on monolayer MoS2 by vdW
epitaxy, with pristine interface and controllable thickness down to
The operation of the C8-BTBT/MoS2 vertical heterojunction devices is highly
tunable by bias and gate voltages between three different regimes:
recombination, tunneling and blocking. The pn junction shows diode-like
behavior with rectifying ratio up to 105 at the room temperature. Our
also exhibit photovoltaic responses with power conversion efficiency of
and photoresponsivity of 22mA/W. With wide material combinations, such
2D structures will offer possibilities for opto-electronic devices that are
possible from individual constituents.

Within the BaFe2As2 crystal lattice, we partially substitute thallium for
barium and report the effects of interlayer coupling in Ba1-xTlxFe2As2
crystals. We demonstrate the unusual effects of magneto-elastic coupling and
charge doping in this iron-arsenide material, whereby Neel temperature rises
with small x, and then falls with additional x. Specifically, we find that
and structural transitions in BaFe2As2 (TN =Ts= 133 K) increase for x=0.05

neutron diffraction measurements. Evidence from single crystal X-ray
diffraction and first principles calculations attributes the stronger
in x=0.05 to magneto-elastic coupling related to the shorter intraplanar
bond distance. With further thallium substitution, the transition
decrease for x = 0.09 (TN = Ts = 131 K), and this is due to charge doping.

Terahertz technology is mature enough for large-volume sensing
However, Dook van Mechelen says there are a few hurdles preventing its
industrial debut. THz spectroscopy has a number of advantages that point to
abundant industrial applications, in areas such quality control, security
biomedical imaging. Yet despite those advantages, the search for a THz
application"--a novel, innovative use with a business case strong enough to
bring the technology into the industrial mainstream--has remained fruitless,
and even the hope of finding such an application has begun to falter. Why
has a
killer app for THz radiation been so elusive? And how can the road to
industrial application of this versatile technology be cleared?

oxygen-deficient SmFeAsO1-x
Authors: Yoshinori Muraba, Soshi Iimura, Satoru Matsuishi, and Hideo Hosono
Categories: cond-mat.supr-con cond-mat.mtrl-sci
We investigated the preferred electron dopants at the oxygen sites of
1111-type SmFeAsO by changing the atmospheres around the precursor with the
composition of Sm:Fe:As:O = 1:1:1:1-x in high-pressure synthesis. Under H2O
H2 atmospheres, hydrogens derived from H2O or H2 molecules were introduced

the H2O and H2 sources were removed from the synthetic process, nearly
stoichiometric SmFeAsO was obtained and the maximum amount of oxygen
introduced remained x = 0.05(4). Density functional theory calculations
indicated that substitution of hydrogen in the form of H- is more stable

Low-temperature thermal conductivity measurements were performed on single
crystal of PbTaSe$_2$, a noncentrosymmetric superconductor with topological
bulk nodal lines in the electronic band structure. It is found that the
residual linear term $\kappa_0/T$ is negligible in zero magnetic field.
Furthermore, the field dependence of $\kappa_0/T$ exhibits a clear
curve. These results suggest that PbTaSe$_2$ has multiple nodeless
superconducting gaps. Therefore, the spin-triplet state with gap nodes does
play an important role in this noncentrosymmetric superconductor with strong
spin-orbital coupling. The fully gapped superconducting state also meets the

long range all-in/all-out antiferromagnetic order below T_N ~ 0.4 K with
propagation vector k = (0 0 0) and an ordered moment of 1.26(2) \mu_B/Nd at
K. The ordered moment is much smaller than the estimated moment of 2.65

For a symmetry consistent theoretical description of the multiferroic
of Ba$_2$CoGe$_2$O$_7$ a precise knowledge of its crystal structure is a
prerequisite. In our previous synchrotron X-ray diffraction experiment on
multiferroic Ba$_2$CoGe$_2$O$_7$ at room temperature we found forbidden
reflections that favour the tetragonal-to-orthorhombic symmetry lowering of
titled compound. Here, we report the results of room-temperature
diffraction studies with both hot and cold neutrons to differentiate between
the real symmetry lowering and multiple diffraction (the Renninger effect).
comparison of the experimental multiple diffraction patterns with simulated
ones rules out the symmetry lowering. Thus, the structural model based on
tetragonal space group $P\bar{4}2_1m$ was selected to describe the
Ba$_2$CoGe$_2$O$_7$ symmetry at room temperature. The precise structural
parameters from neutron diffraction at 300K are presented and compared with
previous X-ray diffraction results.

Title: Quantum Computing with Parafermions

to Majorana fermions, braiding of parafermions with $d>2$ allows to perform
entangling gate. This has spurred interest in parafermions and a variety of

Title: A Micro-foundation of Social Capital in Evolving Social Networks
Authors: Ahmed M. Alaa, Kartik Ahuja, and Mihaela van der Schaar
Categories: cs.SI physics.soc-ph
Comments: Centrality, homophily, network formation, popularity, preferential
attachment, social capital, social networks
A social network confers benefits and advantages on individuals (and on
groups), the literature refers to these advantages as social capital. This
paper presents a micro-founded mathematical model of the evolution of a
network and of the social capital of individuals within the network. The
evolution of the network is influenced by the extent to which individuals
homophilic, structurally opportunistic, socially gregarious and by the
distribution of types in the society. In the analysis, we identify different
kinds of social capital: bonding capital, popularity capital, and bridging
capital. Bonding capital is created by forming a circle of connections,
homophily increases bonding capital because it makes this circle of
more homogeneous. Popularity capital leads to preferential attachment:
individuals who become popular tend to become more popular because others
more likely to link to them. Homophily creates asymmetries in the levels of
popularity attained by different social groups, more gregarious types of
are more likely to become popular. However, in homophilic societies,
individuals who belong to less gregarious, less opportunistic, or major

Title: Modeling the Interplay Between Individual Behavior and Network

V. Chawla
Categories: cs.SI physics.soc-ph
It is well-known that many networks follow a power-law degree
however, the factors that influence the formation of their distributions are
still unclear. How can one model the connection between individual actions
network distributions? How can one explain the formation of group phenomena
their evolutionary patterns?
In this paper, we propose a unified framework, M3D, to model human
in social networks from three perspectives: macro, meso, and micro. At the
micro-level, we seek to capture the way in which an individual user decides
whether to perform an action. At the meso-level, we study how group behavior
develops and evolves over time, based on individual actions. At the
macro-level, we try to understand how network distributions such as
(or heavy-tailed phenomena) can be explained by group behavior. We provide
theoretical analysis for the proposed framework, and discuss the connection
our framework with existing work.
The framework offers a new, flexible way to explain the interplay between
individual user actions and network distributions, and can benefit many
applications. To model heavy-tailed distributions from partially observed
individual actions and to predict the formation of group behaviors, we apply
M3D to three different genres of networks: Tencent Weibo, Citation, and
We also use information-burst prediction as a particular application to
quantitatively evaluate the predictive power of the proposed framework. Our
results on the Weibo indicate that M3D's prediction performance exceeds
that of
several alternative methods by up to 30\%.

constant to the Universe based on Boltzmann probability distribution and the
Holographic principle, a comparison between the zero cosmological constant

contribution of
this paper is that after applying the fundamental theorem of algebra to one
action chosen from the exponential class that derived from the Shaw and
Barrow's works, the Lee-Yang theorem can be applied to the selected action,
meaning that critical phenomena might involve the growth of large-scale
structure of the Universe, and the phase transition phenomena of the

We study the limiting degree distribution of the vertex splitting model
introduced in \cite{DDJS:2009}. This is a model of randomly growing ordered
trees, where in each time step the tree is separated into two components by
splitting a vertex into two, and then inserting an edge between the two new
vertices. Under some assumptions on the parameters, related to the growth of
the maximal degree of the tree, we prove that the vertex degree densities
converge almost surely to constants which satisfy a system of equations.
this we are also able to strengthen and prove some previously non-rigorous
results mentioned in the literature.

We show that complex Langevin simulation converges to a wrong result, by
relating it to the Lefschetz-thimble path integral, when the path-integral
weight has different phases among dominant complex saddle points.
solution of the complex Langevin equation forms local distributions around
complex saddle points. Its ensemble average approximately becomes a direct
of the average in each local distribution, where relative phases among them
dropped. We propose that by taking these phases into account through
reweighting, we can solve the wrong convergence problem. However, this
prescription may lead to a recurrence of the sign problem in the complex
Langevin method for quantum many-body systems.

Title: Rotationally invariant ensembles of integrable matrices
Authors: Emil A. Yuzbashyan, B. Sriram Shastry, Jasen A. Scaramazza
Categories: math-ph cond-mat.stat-mech math.MP
Comments: 10 pages
We construct ensembles of random integrable matrices with any prescribed
number of nontrivial integrals and formulate integrable matrix theory (IMT)
a counterpart of random matrix theory (RMT) for quantum integrable models. A
type-M family of integrable matrices consists of exactly N-M independent
commuting N-by-N matrices linear in a real parameter. We first develop a
rotationally invariant parameterization of such matrices, previously only
constructed in a preferred basis. For example, an arbitrary choice of a
and two commuting Hermitian matrices defines a type-1 family and vice versa.
Higher types similarly involve a random vector and two matrices. The
basis-independent formulation allows us to derive the joint probability
for integrable matrices, in a manner similar to the construction of Gaussian
ensembles in the RMT.

In soft and condensed matter physics, effective interactions often emerge
a result of the spatial confinement of a fluctuating field. For instance,
microscopic particles in a binary liquid mixture are subject to critical
Casimir forces whenever their surfaces confine the thermal fluctuations of
order parameter of this kind of solvent, the range of which diverges upon
approaching the critical demixing point. Critical Casimir forces are
to be nonadditive on a particular large scale. However, a direct
evidence of this fact is still lacking. Here, we fill in this gap by
the experimental measurement of the associated many-body effects. In
particular, we focus on three colloidal particles in optical traps and
that the critical Casimir force exerted on one of them by the other two
colloids differs from the sum of the forces they exert separately. The
magnitude and range of this three-body effect turn out to depend
sensitively on
the distance from the critical point of the solvent and on the preferential
adsorption at the surfaces of the colloids for the two components of the

between q-deformed algebras in two different contexts of Statistical
namely, the Tsallis' framework and the Kaniadakis' scenario, with a local
of fractional-derivative operators for fractal media, the so-called

this paper, we present an extension of the traditional calculus of
for systems containing deformed-derivatives embedded into the Lagrangian and
the Lagrangian densities for classical and field systems. The results extend
the classical Euler-Lagrange equations and the Hamiltonian formalism. The
resulting dynamical equations seem to be compatible with those found in the

systems in classical and quantum mechanics. Examples are presented to
illustrate applications of the formulation. Also, the conserved Nether
