Cherenkov radiation in a strong magnetic field

Physics Letters B, 2020
According to quantum electrodynamics, in a strong magnetic field that is constant and spatially uniform, the vacuum becomes polarized with a refractive index greater than unity.

Cherenkov radiation from electrons passing through human tissue [PDF]

Journal of Innovative Optical Health Sciences, 2017
A method for investigating the optical properties of human tissues is suggested. The method is based on the measurement of Cherenkov radiation produced by relativistic electrons passing through the tissue.

Controlling Cherenkov angles with resonance transition radiation

Nature Physics, 2018
Cherenkov radiation provides a valuable way to identify high energy particles in a wide momentum range, through the relation between the particle velocity and the Cherenkov angle. However, since the Cherenkov angle depends only on material's permittivity,

Evaluation of Cherenkov-induced photodynamic therapy of biohybrid photosensitive graphene oxide nanoplatform in cervical cancer cells [PDF]

Iranian Journal of Basic Medical Sciences
Objective(s): During radiotherapy, weak photons of Cherenkov radiation are generated, which can cause a relative increase in tumor resistance and cause errors in the radiotherapy treatment planning process.

Vacuum Cherenkov radiation at finite temperature

Physics Letters B, 2022
In this paper we examine the thermal effects of the vacuum Cherenkov radiation in a Lorentz- and CPT-violating electrodynamics. We compute the thermal contribution to the Cherenkov radiation rate within the Thermofield Dynamics approach.

Gamma Ray Cherenkov-Transition Radiation [PDF]

EPL (Europhysics Letters), 2013
The production of gamma-ray Cherenkov-transition radiation (GCTR) by charged particles in the photon energy region 0.8 - 2 MeV is studied theoretically using the results of the recent discovery that in the above mentioned region the dielectric constant ...

TACHYONS AND GRAVITATIONAL CHERENKOV RADIATION [PDF]

Modern Physics Letters A, 2011
We calculate the rate at which a free tachyon (faster than light particle) would emit gravitational radiation. It is very small.
