Constraint on ghost-free bigravity from gravitational Cherenkov radiation [PDF]
, 2016 We investigate gravitational Cherenkov radiation in a healthy branch of background solutions in the ghost-free bigravity model. In this model, because of the modification of dispersion relations, each polarization mode can possess subluminal phase ...

Continuously-tunable Cherenkov-radiation-based detectors via plasmon index control
, 2020 A recent study [PRB 100, 075427 (2019)], finally, demonstrated plasmon-analog of refractive index enhancement in metal nanostructures, which has already been studied in atomic clouds for several decades.

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

(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 ...

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.

Broadband and Tunable 920-nm Femtosecond Pulse Generated by an All-Fiber Er:Fiber Laser System
IEEE Access, 2021 Fiber-optic Cherenkov radiation (FOCR) is a promising nonlinear process that is widely used for nonlinear wavelength conversion. In this study, an all-fiber 920-nm femtosecond pulse source is experimentally demonstrated by using Cherenkov radiation.

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.

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 ...

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
