The Gravitational Cherenkov Radiation

open access: yes, 2001
An example of discontinuity of the energy-momentum tensor moving at superluminal velocity is discussed. It is shown that the gravitational Mach cone is formed. The power spectrum of the corresponding Cherenkov radiation is evaluated.

Study of the statistical properties of the detected cosmic rays [PDF]

open access: yesЯдерна фізика та енергетика, 2008
The results of statistic analysis of Cherenkov radiation detection data are presented. Some abnormalities in Fourier and wavelet spectra of the analyzed process have been found.

Gambini-Pullin electrodynamics as a scenario for Cherenkov radiation in QED vacuum

open access: yesPhysics Letters B, 2023
We examine the electromagnetic radiation produced by a moving charge in the QED vacuum that behaves as a dispersive medium characterized by a geometrical structure (discreteness/granularity) that emerges from loop quantum gravity.

Single-mode dispersive waves and soliton microcomb dynamics

open access: yesNature Communications, 2017
Dissipative Kerr solitons in microresonators have recently been shown to generate frequency combs via Cherenkov radiation. Here, Yiet al. demonstrate hysteresis behaviour and a single-mode dispersive wave that can improve the stability of microcombs.
