# Trigger-type metamaterials on the base of collective Jahn-Teller effect

## TL;DR

This paper proposes a method to create trigger-type metamaterials by inserting quantum systems with specific energy spectra into matrices, inducing stepwise Jahn-Teller effects and metastable states for advanced material design.

## Contribution

It introduces a novel approach to induce trigger-type Jahn-Teller effects in metamaterials through quantum system insertion, enabling new metastable states and material functionalities.

## Key findings

- Insertion of quantum systems with specific spectra induces metastable states.
- Stepwise Jahn-Teller effect can be triggered in various matrices.
- Potential for advanced metamaterials development.

## Abstract

Generally, in case of the collective Jahn-Teller effect, a high-symmetry structure of a matrix in which quantum systems with degenerate ground state are inserted becomes distorted. This usually smooth transition can become abrupt only if the matrix by itself is a trigger and JTE merely activates its switching. It is shown in this paper that proper insertion into matrix of quantum systems with the singlet ground state and degenerate excited state leads to the formation of a new metastable state of the whole system and a stepwise appearance of JTE. A matrix of any nature can be transformed into trigger in this way if one manages to synthesize and insert into it proper quantum active centers with appropriate energy spectrum. Theoretically, this provides advanced possibilities for metamaterials development.
