Casimir interaction between absorbing and meta Materials

TL;DR

This paper explores the Casimir energy between dissipative mirrors and suggests that engineered metamaterials could enable repulsive Casimir forces, with implications for nanotechnology and quantum control.

Contribution

It introduces a mode sum approach for Casimir energy with dissipative mirrors and proposes metamaterials as a means to achieve repulsive forces.

Findings

Mode sum formula for dissipative mirrors

Metamaterials may enable repulsive Casimir forces

Potential applications in nanotechnology

Abstract

We investigate the Casimir energy between two dissipative mirrors in term of a sum over mode formula which can be interpreted by analogy to a quantum dissipative oscillator. We also show that metamaterials engineered at scales between the nanometer and the micron seem a promising way to achieve a repulsive force.
