2014-07-08 | Nonminimally coupled scalar field in teleparallel gravity: boson stars | We study the nonminimally coupled complex scalar field within the framework
of teleparallel gravity. Coupling of the field nonminimally to the torsion

2014-09-23 | Thermodynamics of the polaron master equation at finite bias | We study coherent transport through a double quantum dot. Its two electronic
leads induce electronic matter and energy transport and a phonon reservoir
contributes further energy exchanges. By treating the system-lead couplings

non-perturbatively in a polaro... | 1409.6480v2 |
2014-09-23 | Weak Scale From the Maximum Entropy Principle | The theory of multiverse and wormholes suggests that the parameters of the
Standard Model are fixed in such a way that the radiation of the $S^{3}$
universe at the final stage $S_{rad}$ becomes maximum, which we call the
maximum entropy principle. Although it is difficult to confirm this principle
generally, for a few ... | 1409.6508v2 |
2014-09-25 | Delay stabilizes stochastic motion of bumps in layered neural fields | We study the effects of propagation delays on the stochastic dynamics of
bumps in neural fields with multiple layers. In the absence of noise, each
layer supports a stationary bump. Using linear stability analysis, we show that
delayed coupling between layers causes translating perturbations of the bumps
to decay in th... | 1409.7149v2 |
2014-09-26 | Stochastic mean field formulation of the dynamics of diluted neural networks | We consider pulse-coupled Leaky Integrate-and-Fire neural networks with
randomly distributed synaptic couplings. This random dilution induces

step-scaling function at s... | 1410.5886v2 |
2014-11-03 | Rashba coupling and magnetic order in correlated helical liquids | We study strongly correlated helical liquids with and without Rashba coupling
using quantum Monte Carlo simulations of the Kane-Mele model with a Hubbard
interaction at the edge. Independent of the Rashba coupling, we find that
interactions enhance spin correlations and suppress the spectral weight at the
Fermi level. ... | 1411.0719v2 |
2014-11-06 | Mathematica and Fortran programs for various analytic QCD couplings | We outline here the motivation for the existence of analytic QCD models,
i.e., QCD frameworks in which the running coupling $A(Q^2)$ has no Landau
singularities. The analytic (holomorphic) coupling $A(Q^2)$ is the analog of
the underlying pQCD coupling $a(Q^2) \equiv \alpha_s(Q^2)/\pi$, and any such
$A(Q^2)$ defines an... | 1411.1581v1 |

2014-11-09 | Probing anomalous Higgs couplings in $H \to Z V$ decays | We analyze the possibility of probing anomalous Higgs couplings in the rare
decays $H \to Z V$, $V$ being a vector quarkonium state. These rare decays
involve both gauge as well as the Yukawa sectors and either of them can
potentially be anomalous. We show that the branching fractions for $H \to Z V$
decays in Standard... | 1411.2210v2 |
2014-11-10 | State disturbance and pointer shift in protective quantum measurements | We investigate the disturbance of the state of a quantum system in a
protective measurement for finite measurement times and different choices of

fluctuation (MRDF) model to compute the combined effects of electron-electron
and electron-phonon interactions to describe the superconducting dome in the
correlated MoS2 thin flake and TiSe2. We find that without including the
electron-electron ... | 1411.3096v3 |

dimension-six effective Lagrangian, we study the impact of anomalous Higgs
couplings in angular asymmetries of the crossing-symmetric processes H -->
Zl+l- and e+e- --> HZ. In the light of present bounds on d=6 couplings, we show
that some asym... | 1411.3942v1 |
2014-11-15 | Dynamic aerodynamic-structural coupling numerical simulation on the flexible wing of a cicada based on ansys | Most biological flyers undergo orderly deformation in flight, and the
deformations of wings lead to complex fluid-structure interactions. In this
paper, an aerodynamic-structural coupling method of flapping wing is developed
based on ANSYS to simulate the flapping of flexible wing. Fluent module and
Transient Structura... | 1411.4110v2 |

2014-11-20 | Robustness of chimera states for coupled FitzHugh-Nagumo oscillators | Chimera states are complex spatio-temporal patterns that consist of
coexisting domains of spatially coherent and incoherent dynamics. This
counterintuitive phenomenon was first observed in systems of identical
oscillators with symmetric coupling topology. Can one overcome these
limitations? To address this question, we... | 1411.5481v1 |
2014-11-26 | Shadow poles in a coupled-channel problem calculated with Berggren basis | In coupled-channel models the poles of the scattering S-matrix are located on
different Riemann sheets. Physical observables are affected mainly by poles
closest to the physical region but sometimes shadow poles have considerable
effect, too. The purpose of this paper is to show that in coupled-channel
problem all pole... | 1411.7151v2 |
2014-11-27 | Absence of collapse in quantum Rabi oscillations | We show analytically that the collapse and revival in the population dynamics
of the atom-cavity coupled system under the rotating wave approximation (RWA),
valid only at very weak coupling, is an artifact as the atom-cavity coupling is
increased. Even the first-order correction to the RWA is able to bring about
the ab... | 1411.7431v1 |
2014-11-28 | Position-dependent spin-orbit coupling for ultracold atoms | We theoretically explore atomic Bose-Einstein condensates (BECs) subject to
position-dependent spin-orbit coupling (SOC). This SOC can be produced by
cyclically laser coupling four internal atomic ground (or metastable) states in
an environment where the detuning from resonance depends on position. The
resulting spin-o... | 1411.7813v2 |
