(Gravitational) Vacuum Cherenkov Radiation [PDF]
Symmetry, 2018 This work reviews our current understanding of Cherenkov-type processes in vacuum that may occur due to a possible violation of Lorentz invariance. The description of Lorentz violation is based on the Standard Model Extension (SME). To get an overview as general as possible, the most important findings for vacuum Cherenkov radiation in Minkowski ...

Transient Cherenkov radiation from an inhomogeneous string excited by an ultrashort laser pulse at superluminal velocity [PDF]
, 2013 An optical response of one-dimensional string made of dipoles with a periodically varying density excited by a spot of light moving along the string at the superluminal (sub-luminal) velocity is theoretically studied.

Cherenkov radiation of neutrinos
Physics Letters B, 1993 Abstract We consider Cherenkov radiation emitted by neutral particles with a non-zero magnetic and/or electric dipole moment. As an application we estimate the number of photons generated by the solar neutrino flux in water. With an effective neutrino magnetic moment of 10−10 μB around 50 photons in the range of visible light would be produced per ...

Generation of coherent THz Cherenkov radiation by electron bunch tilt control
Physical Review Accelerators and Beams, 2022 We propose a new method that generates coherent Cherenkov radiation by controlling the tilt of the electron bunch. In this scheme, the wavelength band of coherent radiation depends on the transverse size of the electron bunch.

The role of energy-momentum conservation in emission of Cherenkov gluons [PDF]
, 2007 The famous formula for the emission angle of Cherenkov radiation should be modified when applied to hadronic reactions because of recoil effects. They impose the upper limit on the energy of the gluon emitted at a given angle. Also, it leads to essential

Cherenkov Radiation from the Quantum Vacuum [PDF]
Physical Review Letters, 2019 A charged particle moving through a medium emits Cherenkov radiation when its velocity exceeds the phase velocity of light in that medium. Under the influence of a strong electromagnetic field, quantum fluctuations can become polarized, imbuing the vacuum with an effective anisotropic refractive index and allowing the possibility of Cherenkov radiation
