Large distance expansion in the Schrödinger representation of quantum field theory [PDF]
, 1997 This thesis is concerned with an approach to Quantum Field Theory in which the states are constructed from their large distance behaviour. The logarithm of the vacuum functional is expandable as a local quantity in any quantum field theory in which the ...

Basics of thermal field theory: a tutorial on perturbative computations
, 2016 This book presents thermal field theory techniques, which can be applied in both cosmology and the theoretical description of the QCD plasma generated in heavy-ion collision experiments.

Arthritis Care &Research, EarlyView.Systemic sclerosis (SSc) is a rare autoimmune disease defined by immune dysregulation, vasculopathy, and progressive fibrosis of the skin and internal organs. Despite advances in care, major complications such as interstitial lung disease (ILD) and myocardial involvement remain the leading causes of morbidity and mortality.

Energy and momentum dependence of the soft-axion interaction rate
Journal of High Energy PhysicsAxions coupled to thermal non-Abelian gauge fields may have cosmological significance. As the heat bath defines a frame, its influence depends separately on energy and momentum.

Journal of High Energy Physics, 2021 We derive the general exact forms of the Wigner function, of mean values of conserved currents, of the spin density matrix, of the spin polarization vector and of the distribution function of massless particles for the free Dirac field at global ...

Scattering in Geometric Approach to Quantum Theory
, 2022 We define inclusive scattering matrix in the framework of a geometric approach to quantum field theory. We review the definitions of scattering theory in the algebraic approach and relate them to the definitions in the geometric ...

Advanced Engineering Materials, EarlyView.A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Two-loop HTL-resummed thermodynamics for N $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills theory
Journal of High Energy Physics, 2020 We compute the two-loop hard-thermal-loop (HTL) resummed thermodynamic potential for N $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills (SYM). Our final result is manifestly gauge-invariant and was renormalized using only simple vacuum energy, gluon mass,

Eigenstate thermalization hypothesis in conformal field theory [PDF]
Journal of Statistical Mechanics: Theory and Experiment, 2018 Abstract We investigate the eigenstate thermalization hypothesis (ETH) in d + 1 dimensional conformal field theories by studying the reduced density matrices in energy eigenstates.

A Goldstone theorem in thermal relativistic quantum field theory
, 2011 We prove a Goldstone theorem in thermal relativistic quantum field theory, which relates spontaneous symmetry breaking to the rate of spacelike decay of the two-point function. The critical rate of fall-off coincides with that of the massless free scalar
