Thermodynamic fluctuations of electromagnetic field in slightly absorbing media
Condensed Matter Physics, 2004 A theory of thermodynamic fluctuations of electromagnetic field in slightly absorbing media is developed using the quantum electrodynamics - method of $Gamma$-operators - without phenomenology. The hypothesis offered by Yury L.

Fluctuations and response of nonequilibrium states
, 2009 A generalized fluctuation-response relation is found for thermal systems driven out of equilibrium. Its derivation is independent of many details of the dynamics, which is only required to be first-order.

Kinetic Compensation of Barrel Launch Under High‐Speed Solid‐Phase Particulate Impacts
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT An accurate launch‐dynamics computational method is critical for barrel weapon service life assessment and multiphase physics field refinement. Given the lack of studies on the solid‐phase buildup behavior at the projectile base, this paper provides an improved method for calculating the launching dynamics under high pressure and high speed ...

Quantum fluctuation and dissipation in holographic theories: A unifying study scheme
Journal of High Energy Physics, 2018 Motivated by the wide range of applicability of the fluctuation and dissipation phenomena in non-equilibrium systems, we provide a universal study scheme for the dissipation of the energy and the corresponding Brownian motion analysis of massive ...

Non equilibrium statistical physics with fictitious time
, 2005 Problems in non equilibrium statistical physics are characterized by the absence of a fluctuation dissipation theorem. The usual analytic route for treating these vast class of problems is to use response fields in addition to the real fields that are ...

Elastoplasticity Informed Kolmogorov–Arnold Networks Using Chebyshev Polynomials
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Multilayer perceptron (MLP) networks are predominantly used to develop data‐driven constitutive models for granular materials. They offer a compelling alternative to traditional physics‐based constitutive models in predicting non‐linear responses of these materials, for example, elastoplasticity, under various loading conditions. To attain the

Tracer dynamics in an interacting active bath: fluctuations and energy partition
New Journal of PhysicsWe investigate the dynamics of a massive tracer particle coupled to an interacting active bath, modeled as a harmonic chain of overdamped active particles analytically, with an aim to understand the impact of bath interactions and activity on the ...

physica status solidi (b), EarlyView.The response of graphene and MoS2 monolayers to highly‐charged impinging ions is investigated using nonequilibrium Green functions theory. Electronic correlations are found to have a significantly stronger influence on the ultrafast ion‐induced electron dynamics in MoS2 than in graphene.
