A microscopic, non-equilibrium, statistical field theory for cosmic structure formation [PDF]
, 2014 Building upon the recent pioneering work by Mazenko and by Das and Mazenko, we develop a microscopic, non-equilibrium, statistical field theory for initially correlated canonical ensembles of classical microscopic particles obeying Hamiltonian dynamics ...

Inhomogeneous Conformal Field Theory Out of Equilibrium [PDF]
Annales de l'Institute Henri Poincare. Physique theorique, 2019 We study the non-equilibrium dynamics of conformal field theory (CFT) in 1+1 dimensions with a smooth position-dependent velocity v ( x ) explicitly breaking translation invariance. Such inhomogeneous CFT is argued to effectively describe 1+1-dimensional

Perturbative effective field theory expansions for cosmological phase transitions [PDF]
Journal of High Energy Physics, 2023 Guided by previous non-perturbative lattice simulations of a two-step electroweak phase transition, we reformulate the perturbative analysis of equilibrium thermodynamics for generic cosmological phase transitions in terms of effective field theory (EFT)

Entanglement negativity and entropy in non-equilibrium conformal field theory [PDF]
, 2014 We study the dynamics of the entanglement in one-dimensional critical quantum systems after a local quench in which two independently thermalized semi-infinite halves are joined to form a homogeneous infinite system and left to evolve unitarily.

Quantum Mechanics and Quantum Field Theory: Algebraic and Geometric Approaches
, 2023 This is a non-standard exposition of the main notions of quantum mechanics and quantum field theory, including recent results. It is based on the algebraic approach in which the starting point is a star-algebra and on the geometric approach in which the ...

Statistical equilibrium in quantum gravity: Gibbs states in group field theory [PDF]
New Journal of Physics, 2018 Gibbs states are known to play a crucial role in the statistical description of a system with a large number of degrees of freedom. They are expected to be vital also in a quantum gravitational system with many underlying fundamental discrete degrees of ...

Energy flow and fluctuations in non-equilibrium conformal field theory on star graphs [PDF]
, 2013 We consider non-equilibrium quantum steady states in conformal field theory (CFT) on star-graph configurations, with a particular, simple connection condition at the vertex of the graph.

Landau theory for non-equilibrium steady states [PDF]
SciPost Physics, 2019 We examine how non-equilibrium steady states close to a continuous phase transition can still be described by a Landau potential if one forgoes the assumption of analyticity.
