18. A glimpse on higher-loop contributions to the Heisenberg-Euler effective action

Felix Karbstein

In an attempt to obtain any controlled insights into the low-energy effective theory governing the physics of classical electromagnetic fields in the quantum vacuum beyond low loop orders, we study the Heisenberg-Euler effective action in constant electromagnetic fields $\bar{F}$ for quantum electrodynamics (QED) with $N$ charged particle flavors of the same mass and charge $e$ in the large...

33. Coherent radiation of electron bunch traversing laser pulse

Coherency can crucially modify the properties of radiation emitted by many particles compared to a single particle. We study the conditions for coherent radiation of an electron bunch driven by a counterpropagating strong pulsed electromagnetic plane wave [1,2]. We derive the spectrum of the coherent radiation and show that it is emitted backwards with respect to the laser propagation...

39. Quantum simulations for strong field QED

Luis Hidalgo (The University of Illinois)

Quantum field theory in the presence of strong background fields contains interesting problems where quantum computers may someday provide a valuable computational resource. In the noisy intermediate-scale quantum (NISQ) era it is useful to consider simpler benchmark problems in order to develop feasible approaches, identify critical limitations of current hardware, and build new simulation...
