Dynamically and Thermally Nonequilibrium Fluctuation-Electromagnetic Interactions: Recent Results and Trends

TL;DR

This paper reviews recent theoretical advances in fluctuation-electromagnetic interactions involving bodies at different temperatures and motions, covering various configurations and emphasizing the adequacy of the Levin-Polevoi-Rytov theory for friction and heat exchange.

Contribution

It provides a comprehensive summary of recent theoretical developments in nonequilibrium fluctuation-electromagnetic interactions across multiple geometries and confirms the validity of a specific theoretical approach.

Findings

The Levin-Polevoi-Rytov theory accurately describes friction and heat exchange in moving bodies.

Three key configurations are analyzed: small particle with a plate, particle in vacuum, and two plates in relative motion.

Theoretical models are extended to relativistic and nonrelativistic regimes.

Abstract

Our recent theoretical developments related to the nonrelativistic and relativistic fluctuation-electromagnetic interactions of bodies with different temperatures moving translationally and (or) rotationally relative to each other are briefly summarized. Three basic geometrical configurations and physical systems are discussed: "a small particle and a thick plate (i);"a small particle in radiation vacuum background" (ii), and "two thick plates in relative motion (iii) -classical Casimir-Lifshitz configuration with allowance for relative motion and different temperatures of plates. For the third configuration, it is shown that the theory of friction and heat exchange by Levin-Polevoi-Rytov proves to be quite adequate contrary to the settled point of view of many authors.
