Simulating dynamically assisted production of Dirac pairs in gapped graphene monolayers
Ibrahim Akal, Reinhold Egger, Carsten Müller +1
In a vicinity of the Fermi surface, graphene layers with bandgaps allow for closely simulating the vacuum of quantum electrodynamics and, thus, its yet unverified strong-field phen…
Strong-field photoionization in two-center atomic systems
J. Fedyk, A. B. Voitkiv, C. Müller
Photoionization of an atom by a strong laser field in the presence of a spatially well-separated neighboring atom is considered. The laser field frequency is assumed to lie…
Criticality and dominance of axion physics in highly magnetized vacuum
Selym Villalba-Chávez, Anatoly E. Shabad, Carsten Müller
In a constant and homogeneous magnetic background, quantum vacuum fluctuations due to axion-like fields can dominate over those associated with the electron-positron fields. Consid…
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…
