Renormalised thermodynamics for Bose gases from low to critical temperatures
Michael H. Heinrich, Alexander Wowchik, Jürgen Berges
We compute thermodynamic properties of dilute Bose gases using non-perturbative approximations of the two-particle irreducible (2PI) effective action. It is shown how to systematic…
Extracting the symmetries of nonequilibrium quantum many-body systems
Aleksandr N. Mikheev, Viktoria Noel, Ido Siovitz +3
Symmetries play a pivotal role in our understanding of the properties of quantum many-body systems. While there are theorems and a well-established toolbox for systems in thermal e…
Scalable cold-atom quantum simulator for two-dimensional QED
Robert Ott, Torsten V. Zache, Fred Jendrzejewski +1
We propose a scalable analog quantum simulator for quantum electrodynamics (QED) in two spatial dimensions. The setup for the U(1) lattice gauge field theory employs inter-species…
Anomaly-induced dynamical refringence in strong-field QED
Niklas Mueller, Florian Hebenstreit, Jürgen Berges
We investigate the impact of the Adler-Bell-Jackiw anomaly on the nonequilibrium evolution of strong-field quantum electrodynamics (QED) using real-time lattice gauge theory techni…
Early quark production and approach to chemical equilibrium
D. Gelfand, F. Hebenstreit, J. Berges
We perform real-time lattice simulations of out-of-equilibrium quark production in non-Abelian gauge theory in 3+1-dimensions. Our simulations include the backreaction of quarks on…
Schwinger pair production with ultracold atoms
V. Kasper, F. Hebenstreit, M. Oberthaler +1
We consider a system of ultracold atoms in an optical lattice as a quantum simulator for electron-positron pair production in quantum electrodynamics (QED). For a setup in one spat…
Connecting real-time properties of the massless Schwinger model to the massive case
Florian Hebenstreit, Jürgen Berges
Quantum electrodynamics in space-time dimensions is analytically solvable for massless fermions, while no solution is known for massive fermions. Employing the classical-st…
Fermion production from real-time lattice gauge theory in the classical-statistical regime
Valentin Kasper, Florian Hebenstreit, Jürgen Berges
We investigate the real-time dynamics of U(1) and SU(N) gauge theories coupled to fermions on a lattice. While real-time lattice gauge theory is not amenable to standard importance…
Real-time dynamics of string breaking
Florian Hebenstreit, Jürgen Berges, Daniil Gelfand
We study the real-time dynamics of string breaking in quantum electrodynamics in one spatial dimension. A two-stage process with a clear separation of time and energy scales for th…
Simulating fermion production in 1+1 dimensional QED
Florian Hebenstreit, Jürgen Berges, Daniil Gelfand
We investigate fermion--anti-fermion production in 1+1 dimensional QED using real-time lattice techniques. In this non-perturbative approach the full quantum dynamics of fermions i…
Universal Critical Equation of State and the Chiral Phase Transition in QCD
J. Berges
We employ non-perturbative flow equations to compute the equation of state for two flavor QCD within an effective quark meson model. This yields the temperature and quark mass depe…
Two flavor chiral phase transition from nonperturbative flow equations
J. Berges, D. -U. Jungnickel, C. Wetterich
We employ nonperturbative flow equations to compute the equation of state for two flavor QCD within an effective quark meson model. This yields the temperature and quark mass depen…
