Photon-photon interactions in Rydberg-atom arrays [PDF]
Quantum, 2022 We investigate the interaction of weak light fields with two-dimensional lattices of atoms with high lying atomic Rydberg states. This system features different interactions that act on disparate length scales, from zero-range defect scattering of atomic

A photon–photon quantum gate based on Rydberg interactions [PDF]
Nature Physics, 2018 The interaction between Rydberg states of neutral atoms is strong and long-range, making it appealing to put it to use in the context of quantum technologies. Recently, first applications of this idea have been reported in the fields of quantum computation and quantum simulation. Furthermore, electromagnetically induced transparency allows to map these

Photon–Photon Interactions and the Opacity of the Universe in Gamma Rays
Universe, 2021 We discuss the topic of the transparency of the Universe in gamma rays due to extragalactic background light, and its cosmological and physical implications.

Fully - heavy tetraquark production by γγ interactions in hadronic collisions at the LHC
Physics Letters B, 2021 We investigate the production of the fully - heavy tetraquark states T4Q in the γγ interactions present in proton-proton, proton-nucleus and nucleus-nucleus collisions at the CERN Large Hadron Collider (LHC).

Rare leptonic processes induced by massless dark photon
Physics Letters B, 2023 We introduce a dark photon considering a U(1) gauge extension of the standard model in particle physics. Provided that the extra U(1) symmetry is unbroken, the dark photon is massless and has no coupling to the standard electromagnetic current.

Photon-photon interaction in axial channeling [PDF]
Physical Review A, 1994 We investigate the possibility that high-energy photons are channeled, when passing through an oriented single crystal, due to Delbrück scattering. For this purpose the exact electron propagator for the single-string model is constructed. Starting from a separation of variables, we solve the Dirac equation for a cylindrical electrostatic potential. The

Photon-photon interaction and the Schwinger process [PDF]
Physical Review D, 2013 We consider the tunneling processes induced by two-particle collisions. The result derived by the termal bath approach is reproduced by the classical configurations. The Coulomb and Yukawa corrections for the rate of the process are computed.

PHOTON-PHOTON INTERACTION IN STRUCTURED QED VACUUM [PDF]
International Journal of Modern Physics: Conference Series, 2012 In spatially structured strong laser fields, quantum electrodynamical vacuum behaves like a nonlinear Kerr medium with modulated third-order susceptibility where new coherent nonlinear effects arise due to modulation. We consider the enhancement of vacuum polarization and magnetization via coherent spatial vacuum effects in the photon-photon ...

Photon interactions with superconducting topological defects
Physics Letters B, 2021 Using a toy model for the interactions between a defect-forming field and the photon field where the photon becomes massive in the defect core (motivated by recent work on defects in the 2HDM), we study the impact on photon propagation in the background ...

PHOTON – POMERON COUPLING IN HADRONIC INTERACTIONS [PDF]
مجلة جامعة الانبار للعلوم الصرفة, 2012 Pomeron coupling to photons has been analyzed. As the pomeron assumed to couple to hadrons through their constituent quarks and since the photon has no constituent quarks it's coupling to the pomeron is not well known.
