Optical Control of Electronic Topological States
Abstract
A new perspective on light-matter interaction for correlated electron systems: An important goal of modern condensed-matter physics involves the search for states of matter with emergent properties and desirable functionalities. Although the tools for material design remain relatively limited, notable advances have been recently achieved by controlling interactions at heterointerfaces, precise alignment of low-dimensional materials, and the use of extreme pressures. In a Nature Perspective, we featured a paradigm based on controlling light-matter interactions, which provides a way to manipulate and synthesize strongly correlated quantum matter. We considered the case in which both electron-electron and electron-photon interactions are strong and give rise to a variety of phenomena. Photon-mediated superconductivity, cavity fractional quantum Hall physics, and optically driven topological phenomena in low dimensions were among the frontiers discussed in this Perspective, which focused upon a field that we termed 'strongly correlated electron-photon science.'
