Non-equilibrium field theory [PDF]

Nuclear Physics B - Proceedings Supplements, 2000
I discuss various topics in relativistic non-equilibrium field theory related to high energy physics and cosmology. I focus on non-perturbative problems and how they can be treated on the lattice.Comment: Plenary talk given at the 18th International ...

Non-Equilibrium Thermodynamics and Conformal Field Theory [PDF]

Communications in Mathematical Physics, 2016
We present a model independent, operator algebraic approach to non-equilibrium quantum thermodynamics within the framework of two-dimensional Conformal Field Theory. Two infinite reservoirs in equilibrium at their own temperatures and chemical potentials

Non-equilibrium effective field theory and second sound [PDF]

Journal of High Energy Physics, 2021
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 ...

Supersymmetric Field Theory of Non-Equilibrium Thermodynamic System [PDF]

Physica A: Statistical Mechanics and its Applications, 1999
On the basis of Langevin equation the optimal SUSY field scheme is formulated to discribe a non-equilibrium thermodynamic system with quenched disorder and non-ergodicity effects.

Perturbative Non-Equilibrium Thermal Field Theory [PDF]

Physical Review D, 2013
We present a new perturbative formulation of non-equilibrium thermal field theory, based upon non-homogeneous free propagators and time-dependent vertices.

Thermodynamic Properties of Non-Equilibrium States in Quantum Field Theory [PDF]

Annals of Physics, 2001
Within the framework of relativistic quantum field theory, a novel method is established which allows to distinguish non-equilibrium states admitting locally a thermodynamic interpretation.

Non-equilibrium mean-field theories on scale-free networks [PDF]

Journal of Statistical Mechanics: Theory and Experiment, 2009
Many non-equilibrium processes on scale-free networks present anomalous critical behavior that is not explained by standard mean-field theories. We propose a systematic method to derive stochastic equations for mean-field order parameters that implicitly

Non-Equilibrium Time Evolution in Quantum Field Theory [PDF]

Physical Review E, 1997
The time development of equal-time correlation functions in quantum mechanics and quantum field theory is described by an exact evolution equation for generating functionals.

Thermalization and pinch singularities in non-equilibrium quantum field theory [PDF]

Physics Letters B, 1994
I argue that, within the Closed-Time-Path formalism, pinch singularities do not appear in truly out of equilibrium situations.Comment: 9 pages, plain TEX, no figures (TEX mistakes ...

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 ...
