Insurgent Metamaterials: light transmission by forbidden transitions

TL;DR

This paper introduces insurgent metamaterials, hyperbolic media with quantum emitters having forbidden optical transitions, leading to unique electromagnetic responses distinct from conventional hyperbolic media.

Contribution

The paper presents the concept of insurgent metamaterials and analyzes their unique electromagnetic properties due to forbidden optical transitions.

Findings

Distinct electromagnetic response compared to conventional hyperbolic media

Potential experimental signatures of the predicted effects

Introduction of a new class of hyperbolic materials

Abstract

We introduce the concept of the ``insurgent metamaterial'' -- which is a hyperbolic medium that contains quantum emitters with a forbidden optical transition. We show that the resulting electromagnetic response of the composite is dramatically different from that expected from the ``conventional'' hyperbolic medium, and discuss the experimental manifestations of the predicted effect.
