Pulse shape optimization for electron-positron production in rotating fields
François Fillion-Gourdeau, Florian Hebenstreit, Denis Gagnon +1
We optimize the pulse shape and polarization of time-dependent electric fields to maximize the production of electron-positron pairs via strong field quantum electrodynamics proces…
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…
The inverse problem for Schwinger pair production
Florian Hebenstreit
The production of electron-positron pairs in time-dependent electric fields (Schwinger mechanism) depends non-linearly on the applied field profile. Accordingly, the resulting mome…
Optimization of Schwinger pair production in colliding laser pulses
Florian Hebenstreit, François Fillion-Gourdeau
Recent studies of Schwinger pair production have demonstrated that the asymptotic particle spectrum is extremely sensitive to the applied field profile. We extend the idea of the d…
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…
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…
Optimizing the pulse shape for Schwinger pair production
Christian Kohlfürst, Mario Mitter, Gregory von Winckel +2
Recent studies of the dynamically assisted Schwinger effect have shown that particle production is significantly enhanced by a proper choice of the electric field. We demonstrate t…
Pair production: the view from the lightfront
Florian Hebenstreit, Anton Ilderton, Mattias Marklund
We give an exact, analytic, and manifestly gauge invariant account of pair production in combined longitudinal and transverse electromagnetic fields, both depending arbitrarily on…
Schwinger effect in inhomogeneous electric fields
Florian Hebenstreit
The vacuum of quantum electrodynamics is unstable against the formation of many-body states in the presence of an external electric field, manifesting itself as the creation of ele…
Particle self-bunching in the Schwinger effect in spacetime-dependent electric fields
Florian Hebenstreit, Reinhard Alkofer, Holger Gies
Non-perturbative electron-positron pair creation (Schwinger effect) is studied based on the equal-time Wigner formalism in 1+1 dimensions. An ab initio calculation of the Schwinger…
Momentum Spectra for Dynamically Assisted Schwinger Pair Production
Markus Orthaber, Florian Hebenstreit, Reinhard Alkofer
Recently the dynamically assisted Schwinger mechanism, i.e., electron-positron pair production from vacuum by a combination of laser pulses with different time scales has been prop…
Strong field effects in laser pulses: the Wigner formalism
Florian Hebenstreit, Anton Ilderton, Mattias Marklund +1
We investigate strong field vacuum effects using a phase space approach based on the Wigner formalism. We calculate the Wigner function in a strong null-field background exactly, u…
