Theory of electron spectroscopies in strongly correlated semiconductor quantum dots

TL;DR

This paper reviews electron spectroscopies in strongly correlated semiconductor quantum dots, predicting that inelastic light scattering and tunneling imaging can reveal signatures of Wigner crystallization.

Contribution

It introduces theoretical predictions that specific spectroscopic techniques can detect electron crystallization in quantum dots.

Findings

Inelastic light scattering can identify crystallization signatures.

Tunneling imaging can visualize electron arrangements.

Strong correlation effects are observable via proposed spectroscopies.

Abstract

Quantum dots may display fascinating features of strong correlation such as finite-size Wigner crystallization. We here review a few electron spectroscopies and predict that both inelastic light scattering and tunneling imaging experiments are able to capture clear signatures of crystallization.
