Linear Breit-Wheeler pair production by high-energy bremsstrahlung photons colliding with an intense X-ray laser pulse
Alina Golub, Selym Villalba-Chávez, Hartmut Ruhl +1
A possible setup for the experimental verification of linear Breit-Wheeler pair creation of electrons and positrons in photon-photon collisions is studied theoretically. It combine…

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…

Axion-modified photon propagator, Coulomb potential and Lamb-shift
Selym Villalba-Chávez, Alina Golub, Carsten Müller
A consistent renormalization of a quantum theory of axion-electrodynamics requires terms beyond the minimal coupling of two photons to a neutral pseudoscalar field. This procedure…
