Universality of quantum information in chaotic CFTs
Journal of High Energy Physics, 2018 We study the Eigenstate Thermalization Hypothesis (ETH) in chaotic conformal field theories (CFTs) of arbitrary dimensions. Assuming local ETH, we compute the reduced density matrix of a ball-shaped subsystem of finite size in the infinite volume limit ...

Equilibrium States in Thermal Field Theory and in Algebraic Quantum Field Theory [PDF]
Annales Henri Poincaré, 2019 In this paper we compare the construction of equilibrium states at finite temperature for self-interacting massive scalar quantum field theories on Minkowski spacetime proposed by Fredenhagen and Lindner with results obtained in ordinary thermal field theory, by means of real time and Matsubara formalisms. In the construction of this state, even if the

Global symmetries and partial confinement
Journal of High Energy Physics, 2022 In gauge theories, spontaneous breaking of the centre symmetry provides a precise definition of deconfinement. In large-N gauge theories, evidence has emerged recently that between confined and deconfined phases a partially-deconfined phase can appear ...

QED symmetries in real-time thermal field theory [PDF]
, 1996 We study the discrete and gauge symmetries of Quantum Electrodynamics at finite temperature within the real-time formalism. The gauge invariance of the complete generating functional leads to the finite temperature Ward identities.

Mean-field theory of failed thermalizing avalanches
Physical Review B, 2022 We show that localization in quasiperiodically modulated, two-dimensional systems is stable to the presence of a finite density of ergodic grains. This contrasts with the case of randomly modulated systems, where such grains seed thermalizing avalanches.

Some information theoretic aspects of de-Sitter holography
Journal of High Energy Physics, 2020 Built on our observation that entangling surfaces of the boundary field theory are great co-dimension one spheres in the context of DS/dS correspondence, we study some information theoretic quantities of the field theory dual intensively using ...

Kubo formulas for thermodynamic transport coefficients
Journal of High Energy Physics, 2018 Uncharged relativistic fluids in 3+1 dimensions have three independent thermodynamic transport coefficients at second order in the derivative expansion. Fluids with a single global U(1) current have nine, out of which seven are parity preserving.

Two problems in thermal field theory
, 2000 In this talk, I review recent progress made in two areas of thermal field theory. In particular, I discuss various approaches for the calculation of the quark gluon plasma thermodynamical properties, and the problem of its photon production rate.Comment:
