A Goldstone Theorem in Thermal Relativistic Quantum Field Theory [PDF]

, 2010
We prove a Goldstone Theorem in thermal relativistic quantum field theory, which relates spontaneous symmetry breaking to the rate of space-like decay of the two-point function.

Advances in perturbative thermal field theory [PDF]

, 2003
The progress of the last decade in perturbative quantum field theory at high temperature and density made possible by the use of effective field theories and hard-thermal/dense-loop resummations in ultrarelativistic gauge theories is reviewed.

Feynman rules for forced wave turbulence

Journal of High Energy Physics, 2023
It has long been known that weakly nonlinear field theories can have a late-time stationary state that is not the thermal state, but a wave turbulent state with a far-from-equilibrium cascade of energy.

Interplay between improved interaction rates and modified cosmological histories for dark matter

Frontiers in Physics, 2023
A novel particle has been and still is an intriguing option to explain the strong evidence for dark matter in our universe. To quantitatively predict the dark matter energy density, two main ingredients are needed: interaction rates and the history of ...

Determining all thermodynamic transport coefficients for an interacting large N quantum field theory

Journal of High Energy Physics, 2023
Thermodynamic transport coefficients can be calculated directly from quantum field theory without requiring analytic continuation to real time. We determine all second-order thermodynamic transport coefficients for the uncharged N-component massless ...

Thermal Effects in Ising Cosmology

Universe, 2023
We consider a real scalar field in de Sitter background and compute its thermal propagators. We propose that in a dS/CFT context, nontrivial thermal effects as seen by an ‘out’ observer can be encoded in the anomalous dimensions of the d=3 Ising model ...

Holographic thermal correlators: a tale of Fuchsian ODEs and integration contours

Journal of High Energy Physics, 2023
We analyze real-time thermal correlation functions of conserved currents in holographic field theories using the grSK geometry, which provides a contour prescription for their evaluation.

Bose-Einstein correlations in thermal field theory [PDF]

, 1995
Two-particle correlation functions are calculated for bosons emitted from a localized thermal source (the ``glow'' of a ``hot spot''). In contrast to existing work, non-equilibrium effects up to first order in gradients of the particle distribution ...

Spectral form factor of a quantum spin glass

Journal of High Energy Physics, 2022
It is widely expected that systems which fully thermalize are chaotic in the sense of exhibiting random-matrix statistics of their energy level spacings, whereas integrable systems exhibit Poissonian statistics.
