Anti-shielding Effect and Negative Temperature in Instantaneously Reversed Electric Fields and Left-Handed Media

TL;DR

This paper explores how anti-shielding effects and negative absolute temperatures in reversed electric fields and left-handed media can lead to superluminal light propagation, linking negative temperature states to electromagnetic phenomena.

Contribution

It introduces the concept that negative absolute temperature states caused by instantaneously reversed electric fields can induce superluminal light propagation in anti-shielding dielectrics and left-handed media.

Findings

Negative absolute temperature states can occur in reversed electric fields.

Such states may cause electromagnetic fields to acquire imaginary mass.

Potential superluminal light propagation in these media is suggested.

Abstract

The connections between the anti-shielding effect, negative absolute temperature and superluminal light propagation in both the instantaneously reversed electric field and the left-handed media are considered in the present paper. The instantaneous inversion of the exterior electric field may cause the electric dipoles into the state of negative absolute temperature and therefore give rise to a negative effective mass term of electromagnetic field (i. e., the electromagnetic field propagating inside the negative-temperature medium will acquire an imaginary rest mass), which is said to result in the potential superluminality effect of light propagation in this anti-shielding dielectric. In left-handed media, such phenomena may also arise.
