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 ...

Spectral Flow in 3D Flat Spacetimes [PDF]

, 2017
In this paper we investigate spectral flow symmetry in asymptotically flat spacetimes both from a gravity as well as a putative dual quantum field theory perspective.

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.

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 ...

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.

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.

Kinetic vs. Thermal-Field-Theory Approach to Cosmological Perturbations [PDF]

, 1994
A closed set of equations for the evolution of linear perturbations of homogeneous, isotropic cosmological models can be obtained in various ways. The simplest approach is to assume a macroscopic equation of state, e.g.\ that of a perfect fluid.

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 ...
