Abstract
Strong coupling between light and excitations of a two-dimensional electron gas (2DEG) are important to both pure physics and to the development of future photonic nanotechnologies. Studying the relationship between spin polarisation of a 2DEG in monolayer semiconductor MoSe2, and resultant light-matter interactions modified by a zero-dimensional optical microcavity, finds the robust spin-susceptibility of the 2DEG simultaneously enhances/supresses trion-polariton formation in opposite photon helicities. This leads to optical non-linearities arising from the highly non-linear behaviour of the valley-specific strong light-matter coupling regime and allowing all-optical tuning of the enhanced polaritonic Zeeman splitting from 4 to more than 10 meV. https://www.nature.com/articles/s41566-022-01025-8
