Effects of Weakly Interacting Slim Particles in Cavities with a Moving Boundary Condition

TL;DR

This paper investigates how a moving boundary in microwave cavities can induce parametric resonance, significantly boosting the conversion probability of Weakly Interacting Slim Particles into photons, with potential experimental implications.

Contribution

It introduces a novel setup with a harmonically oscillating boundary to enhance WISP-photon conversion via parametric resonance in microwave cavities.

Findings

Parametric resonance can amplify conversion probability by several orders of magnitude.

Moving boundary conditions can be effectively used to detect Weakly Interacting Slim Particles.

The study provides a theoretical foundation for experimental searches using dynamic cavity boundaries.

Abstract

We study a Light Shinning Through the wall type setup with microwave cavities, where the regeneration cavity has a moving boundary condition oscillating harmonically. We find a parametric resonance that could enhance the probability conversion between Weakly Interacting Slim Particles and photons by several orders of magnitude.
