Time evolution of correlation functions in non-equilibrium field theories [PDF]
Physics Letters B, 1997 We investigate the non-equilibrium properties of an N-component scalar field theory. The time evolution of the equal-time correlation functions for an arbitrary ensemble of initial conditions is described by an exact functional differential equation.

The Union of Quantum Field Theory and Non-Equilibrium Thermodynamics [PDF]
, 2018 Quantum field theory is the language used to describe nature at its most fundamental scales; while thermodynamics is a framework to describe the collective behavior of macroscopic systems.

Thermodynamic properties of non-equilibrium states in quantum field theory [PDF]
Annals of Physics, 2002 Within the framework of relativistic quantum field theory, a novel method is established which allows for distinguishing non-equilibrium states admitting locally a thermodynamic interpretation.

Perturbative Non-Equilibrium Thermal Field Theory [PDF]
Physical Review D, 2012 We present a new perturbative formulation of nonequilibrium thermal field theory, based upon nonhomogeneous free propagators and time-dependent vertices.

Non-equilibrium conformal field theories with impurities [PDF]
Journal of Physics A: Mathematical and Theoretical, 2015 We present a construction of non-equilibrium steady states within conformal field theory. These states sustain energy flows between two quantum systems, initially prepared at different temperatures, whose dynamical properties are represented by two ...

LOCAL MOLECULAR FIELD THEORY FOR NON-EQUILIBRIUM SYSTEMS [PDF]
, 2019 Local Molecular Field (LMF) theory is a framework for modeling the long range forces of a statistical system using a mimic system with a modified Hamiltonian that includes a self consistent molecular potential.

Cumulants in perturbation expansions for non-equilibrium field theory [PDF]
Nuclear Physics A, 1996 Abstract The formulation of perturbation expansions for a quantum field theory of strongly interacting systems in a general non-equilibrium state is discussed. Non-vanishing initial correlations are included in the formulation of the perturbation expansion in terms of cumulants.

Non-equilibrium effective field theory and second sound [PDF]
Journal of High Energy Physics, 2020 We investigate the phenomenon of second sound in various states of matter from the perspective of non-equilibrium effective field theory (EFT). In particular, for each state of matter considered, we find that at least two (though sometimes multiple ...

Linear response in large deviations theory: a method to compute non-equilibrium distributions [PDF]
, 2021 We consider thermodynamically consistent autonomous Markov jump processes displaying a macroscopic limit in which the logarithm of the probability distribution is proportional to a scale-independent rate function (i.e.

THERMAL FIELD THEORY IN NON-EQUILIBRIUM STATES [PDF]
International Journal of Modern Physics B, 1996 Conventional transport theory is not really applicable to nonequilibrium systems which exhibit strong quantum effects. We present two different approaches to overcome this problem. Firstly we point out how transport equations may be derived that incorporate a nontrivial spectral function as a typical quantum effect, and test this approach in a toy ...
