The production of electron-positron pairs in time-dependent electric fields (Schwinger mechanism) depends non-linearly on the applied field profile. Accordingly, the resulting momentum spectrum is extremely sensitive to small variations of the field

Solvable Markovian dynamics of lattice quantum spin models

Autor: Florian Hebenstreit, David Mesterházy

Publikováno v: Physical Review A. 96

We address the real-time dynamics of lattice quantum spin models coupled to single or multiple Markovian dissipative reservoirs using the method of closed hierarchies of correlation functions. This approach allows us to solve a number of quantum spin

We discuss the experimental engineering of model systems for the description of quantum electrodynamics (QED) in one spatial dimension via a mixture of bosonic 23Na and fermionic 6Li atoms. The local gauge symmetry is realized in an optical superlatt

Anomaly-induced dynamical refringence in strong-field QED

Autor: 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 techniques. For field strengths exceeding the Schwinger limit for pair produ

Early quark production and approach to chemical equilibrium

Autor: Jürgen Berges, Daniil Gelfand, Florian Hebenstreit

We perform real-time lattice simulations of out-of-equilibrium quark production in non-Abelian gauge theory in 3 þ 1 dimensions. Our simulations include the backreaction of quarks onto the dynamical gluon sector, which is particularly relevant for s
