Abstract

The emergence of van der Waals (vdW) magnets with strongly coupled electronic and spin degrees of freedom offers an intriguing platform to study light-matter interaction in low-dimensional magnets. Specifically, magnetic materials that host excitons in the visible frequencies with strong correlation to underlying magnetic order are very attractive in this context. I will present our recent work on realizing exciton-polaritons (strongly coupled light-matter states) in such magnetic systems and the prospects of controlling the magneto-optical response with light [1, 2]. I will conclude with a discussion on realizing active nanophotonic devices using vdW magnets. [1] “Observation of spin-correlated exciton-polaritons in a van der Waals magnet, F. Dirnberger, et al.
