Superradiance by ferroelectrics in cavity resonators

TL;DR

This paper presents a theoretical model demonstrating that ferroelectrics in cavity resonators can produce superradiant pulses when prepared in a nonequilibrium state, with polarization waves initiating the process.

Contribution

It introduces a new theory explaining superradiance in ferroelectrics within cavity resonators, highlighting the role of polarization dipolar waves as triggers.

Findings

Ferroelectrics can emit superradiant infrared pulses under specific conditions.

Polarization dipolar waves act as the trigger for superradiance.

The theory predicts coherent pulse emission from nonequilibrium states.

Abstract

A theory is presented showing that, under appropriate conditions, a ferroelectric in a cavity resonator can emit superradiant pulses. Initially, the ferroelectric has to be prepared in a nonequilibrium state from which it relaxes emitting a coherent pulse in the infrared region. Polarization dipolar waves play the role of the triggering mechanism initiating the beginning of the process.
