Modular invariance and thermal effective field theory in CFT

Journal of High Energy Physics
We use thermal effective field theory to derive that the coefficient of the first subleading piece of the thermal free energy, c 1, is equal to the coefficient of the subleading piece of the Casimir energy on S 1 × S d−2 for d ≥ 4.

Introduction to thermal field theory [PDF]

International Journal of Modern Physics A, 1993
This is intended to be a very basic introduction and short (and of course incomplete) overview of thermal field theory. In the first part, I introduce the thermal propagator at a very simple level and give the Feynman rules using the time-path contour ...

Thermal quantum gravity condensates in group field theory cosmology [PDF]

Physical Review D, 2020
The condensate cosmology programme of group field theory quantum gravity has produced several interesting results. The key idea is in the suggestion that a macroscopic homogeneous spacetime can be approximated by a dynamical condensate phase of the ...

Leontovich Relations in Thermal Field Theory [PDF]

The European Physical Journal C, 2000
The application of generalized Kramers-Kronig relations, the so-called Leontovich relations, to thermal field theory is discussed. Medium effects contained in the full, thermal propagators can easily be taken into account by this method.

Thermal field theory

, 1996
Relativistic thermal field theory gives the theoretical framework for the description of the quark-gluon plasma, a new state of matter whose existence is predicted by lattice gauge theory and which might be produced in collisions of ultrarelativistic ...

Thermal equilibrium states in perturbative Algebraic Quantum Field Theory in relation to Thermal Field Theory

, 2019
In the first part, we analyse the properties of an interacting, massive scalar field in an equilibrium state over Minkowski spacetime. We compare the known real- and imaginary-time formalisms of Thermal Field Theory with the recent construction by ...

Scalar thermal field theory for a rotating plasma

European Physical Journal C: Particles and Fields
This paper initiates the systematic study of thermal field theory for generic equilibrium density matrices, which feature arbitrary values not only of temperature and chemical potentials, but also of average angular momentum.

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)
