Thermal mean-field theories

The Journal of Chemical Physics
Several closely related ab initio thermal mean-field theories for fermions, both well-established and new ones, are compared with one another at the formalism level and numerically. The theories considered are Fermi–Dirac theory; thermal Hartree–Fock (HF) theory; two modifications of the thermal single-determinant approximation of Kaplan and Argyres ...

Inhomogeneous Thermalization in Strongly Coupled Field Theories [PDF]

Physical Review Letters, 2013
To describe theoretically the creation and evolution of the quark-gluon plasma, one typically employs three ingredients: a model for the initial state, non-hydrodynamic early time evolution, and hydrodynamics. In this paper we study the non-hydrodynamic early time evolution using the AdS/CFT correspondence in the presence of inhomogeneities.

Nambu-Goldstone Mechanism in Real-Time Thermal Field Theory [PDF]

, 1999
In a one-generation fermion condensate scheme of electroweak symmetry breaking, it is proven based on Schwinger-Dyson equation in the real-time thermal field theory in the fermion bubble diagram approximation that, at finite temperature $T$ below the ...

Remarks on the influence of quantum vacuum fluctuations over a charged test particle near a conducting wall

Journal of High Energy Physics, 2019
Quantum vacuum fluctuations of the electromagnetic field in empty space seem not to produce observable effects over the motion of a charged test particle.

Unruh quantum Otto engine in the presence of a reflecting boundary

Journal of High Energy Physics, 2022
We introduce a new model of relativistic quantum analogue of the classical Otto engine in the presence of a perfectly reflecting boundary. A single qubit acts as the working substance interacting with a massless quantum scalar field, with the boundary ...

Selected issues in thermal field theory [PDF]

Nuclear Physics A, 2014
New developments on hot and dense QCD in effective field theories are reviewed. Recent investigations in lattice gauge theories for the low-lying Dirac eigenmodes suggest survival hadrons in restored phase of chiral symmetry. We discuss expected properties of those bound states in a medium using chiral approaches.

Spectra of correlators in the relaxation time approximation of kinetic theory

Journal of High Energy Physics
The relaxation time approximation (RTA) of the kinetic Boltzmann equation is likely the simplest window into the microscopic properties of collective real-time transport.

On field theory thermalization from gravitational collapse [PDF]

Journal of High Energy Physics, 2012
Motivated by its field theory interpretation, we study gravitational collapse of a minimally coupled massless scalar field in Einstein gravity with a negative cosmological constant. After demonstrating the accuracy of the numerical algorithm for the questions we are interested in, we investigate various aspects of the apparent horizon formation.
