Controlling topological phases of matter with quantum light

O. Dmytruk and M. Schiro

This paper by Olesia Dmytruk and Marco Schiro explores the fascinating interplay between quantum light and topological properties in quantum matter. They reveal how a simple SSH model can undergo topological phase transitions influenced by light, offering insights into phase changes that could transform our understanding of lattice geometry and light-matter interactions.

Abstract
This paper investigates the control of topological properties of quantum matter using quantum light, specifically focusing on a one-dimensional Su-Schrieffer-Heeger (SSH) model coupled to a single-mode cavity. The authors demonstrate that quantum light can induce topological phase transitions, converting a trivial phase into a topological one and vice-versa, depending on the lattice geometry and light-matter coupling strength. The disappearance of the lower polariton branch at the topological transition point is identified as a potential probe for this transition.
