Dimuon and ditau production in photon-photon collisions at next-to-leading order in QED by Hua-Sheng Shao, David d’Enterria

“…Abstract Next-to-leading-order (NLO) quantum electrodynamics (QED) corrections to the production of muon and tau pairs in photon-photon collisions, γγ → μ + μ − , τ + τ − , are calculated in the equivalent photon approximation. …”

Electro-optic cavities for in-situ measurement of cavity fields by Michael S. Spencer, Joanna M. Urban, Maximilian Frenzel, Niclas S. Mueller, Olga Minakova, Martin Wolf, Alexander Paarmann, Sebastian F. Maehrlein

“…Electro-optic cavities (EOCs) will therefore serve as integrated probes of light-matter interactions across all coupling regimes, laying the foundation for field-resolved intra-cavity quantum electrodynamics.…”

Below the Schwinger critical magnetic field value, quantum vacuum and gamma-ray bursts delay by Iver H. Brevik, Moshe M. Chaichian, Anca Tureanu

“…Above the critical magnetic field limit, calculated by Schwinger in the lowest order perturbation in quantum electrodynamics (QED), one reaches the threshold for electron-positron pair creation (through the intermediate electric field, as known also from standard electrodynamics), which has interesting consequences. …”

Particle motion and QPOs around Euler-Heisenberg black hole immersed in cold dark matter halo by G. Mustafa, S.K. Maurya, Tayyab Naseer, Arzu Cilli, Ertan Güdekli, Assmaa Abd-Elmonem, Neissrien Alhubieshi

“…This black hole solution is characterized by five parameters, namely, the black hole mass M, the feature radius R, the parameter ρ describing the density of the cold dark matter halo, the quantum electrodynamics parameter α, and the black hole charge Q. …”
