Cherenkov Radiation Effect in a Line of Point Charges

Cherenkov Radiation Effect in a Line of Point Charges

A newly published study suggests that the interaction between a surface and a charge packet moving parallel to it can become repulsive above a critical relativistic energy. These findings could potentially impact fundamental electrodynamics, accelerator physics and electron spectroscopy.

Discovery of Magnetic Field That Can Flip Heat Flow


Scientists discovered a magnetic field that can control the flow of heat from one body to another. It was first predicted 50 years ago, and its effect could someday lead to a new generation of electronic devices that use heat rather than charge to carry information.
