Cherenkov radiation of light bullets [PDF]
Physical Review A, 2019 Electrically charged particles, moving faster than the speed of light in a medium, emit Cherenkov radiation. Theory predicts electric and magnetic dipoles to radiate as well, with a puzzling behavior for magnetic dipoles pointing in transversal direction [I. M. Frank, Izv. Akad. Nauk SSSR, Ser. Fiz. 6, 3 (1942)].

Cherenkov-Channeling radiation from sub-GeV relativistic electrons
Physics Letters B, 2019 Quantization of transverse energy levels for planar channeled relativistic electrons together with crystal dispersion may drastically change Cherenkov radiation resulting in mixed Cherenkov-Channeling Radiation (ChCR).

Sources of Low-Energy Events in Low-Threshold Dark-Matter and Neutrino Detectors
Physical Review X, 2022 We discuss several low-energy backgrounds to sub-GeV dark-matter searches, which arise from high-energy particles of cosmic or radioactive origin that interact with detector materials. We focus, in particular, on Cherenkov radiation, transition radiation,

Cherenkov Radiation from $e^+e^-$ Pairs and Its Effect on $\nu_e$ Induced Showers [PDF]
, 2005 We calculate the Cherenkov radiation from an $e^+e^-$ pair at small separations, as occurs shortly after a pair conversion. The radiation is reduced (compared to that from two independent particles) when the pair separation is smaller than the wavelength

Detection of ultra high energy cosmic rays and neutrinos with lunar orbital radio telescope
European Physical Journal C: Particles and Fields, 2023 Particle cascades induced by ultra-high-energy (UHE) cosmic rays and neutrinos impacting on the lunar regolith usually radiate Cherenkov radio emissions due to the presence of excess negative charge, which is known as Askaryan effect. Several experiments

Chiral Cherenkov and chiral transition radiation in anisotropic matter [PDF]
, 2018 A significant contribution to the electromagnetic radiation by a fast electric charge moving in anisotropic chiral matter arises from spontaneous photon radiation due to the chiral anomaly.

Characterization of a practically designed plastic scintillation plate dosimeter. [PDF]
Med PhysAbstract Background Advancements in radiotherapy have enabled the use of high‐definition irradiation, leading to more precise and finely adjusted treatments in clinical settings. Nevertheless, the attainment of high resolution, an extensive measurement area, and the repeatability of dose distribution measurements persist as challenges in clinical ...
