Muon pair production in electron-positron collisions close to threshold in the presence of a strong laser field
N. Mahlin, S. Villalba-Chávez, C. Müller
Within the framework of strong-field quantum electrodynamics, we study the creation of muon-antimuon pairs in laser-assisted collisions of electrons with positrons, whose center-of…
Entering the overcritical regime of nonlinear Breit-Wheeler pair production in collisions of bremsstrahlung -rays and superintense, tightly focused laser pulses
I. Elsner, A. Golub, S. Villalba-Chávez +1
Near-future high-intensity lasers offer prospects for the observation of nonlinear Breit-Wheeler pair production in an overcritical field regime, where the quantum nonlinearity par…
Dynamically-assisted nonlinear Breit-Wheeler pair production in bichromatic laser fields of circular polarization
N. Mahlin, S. Villalba-Chávez, C. Müller
Production of electron-positron pairs by a high-energy photon and a bichromatic laser wave is considered where the latter is composed of a strong low-frequency and a weak high-…
Light-amplified Landau-Zener conductivity in gapped graphene monolayers: a simulacrum of photo-catalyzed vacuum instability
Selym Villalba-Chávez, Oliver Mathiak, Reinhold Egger +1
Interband transitions of electrons in a gapped graphene monolayer are highly stimulated near the Fermi surface when a high-frequency electric wave of weak intensity and a strong co…
Dimensionality-driven photoproduction of massive Dirac pairs near threshold in gapped graphene monolayers
A. Golub, R. Egger, C. Müller +1
Generation of quasi-particle--hole pairs in gapped graphene monolayers in the combined field of two counterpropagating light waves is studied. The process represents an analogue of…
Two-color phase-of-the-phase spectroscopy applied to nonperturbative electron-positron pair production in strong oscillating electric fields
J. Braß, R. Milbradt, S. Villalba-Chávez +2
Production of electron-positron pairs from vacuum in strong bichromatic electric fields, oscillating in time with a fundamental frequency and its second harmonic, is studied. Stron…
Electron-positron pair production in oscillating electric fields with double-pulse structure
L. F. Granz, O. Mathiak, S. Villalba-Chávez +1
Electron-positron pair production from vacuum in a strong electric field oscillating in time is studied. The field is assumed to consist of two consecutive pulses, with variable ti…
Spin effects in strong-field laser-electron interactions
S. Ahrens, T. O. Müller, S. Villalba-Chávez +2
The electron spin degree of freedom can play a significant role in relativistic scattering processes involving intense laser fields. In this contribution we discuss the influence o…
Axion-induced birefringence effects in laser driven nonlinear vacuum interaction
Selym Villalba-Chávez, Antonino Di Piazza
The propagation of a probe electromagnetic field through a counterpropagating strong plane wave is investigated. The effects of the electromagnetic field-(pseudo)scalar axion field…
QED with external field: Hamiltonian treatment for anisotropic medium formed by the Lorentz-non-invariant vacuum
Selym Villalba-Chavez, Anatoly E. Shabad
Nonlinear electrodynamics, QED included, is considered against the Lorentz-noninvariant external field background, treated as an anisotropic medium. Hamiltonian formalism is applie…

Helios Sanchis-Alepuz, Gernot Eichmann, Selym Villalba-Chavez +1
We present the solution of the Poincare-covariant Faddeev equation for the Delta(1232) and Omega(1672) baryons. The covariant structure of the corresponding baryon amplitudes and t…
The role of photon polarization modes in the magnetization and instability of the vacuum in a supercritical field
Selym Villalba-Chavez
The response of the QED vacuum in an asymptotically large electromagnetic field is studied. In this regime the vacuum energy is strongly influenced by the vacuum polarization effec…
