The strong coupling of light and matter can give rise to hybrid quasiparticles known as polaritons, which possess combined properties from both entities.

In this tutorial, I will provide an introduction to exciton-polaritons, which emerge from the coupling of excitons (electron-hole pairs) in semiconductors with photons in a cavity. These polaritons exhibit intriguing characteristics such as a significantly reduced effective mass and enhanced interactions. We will explore various platforms and discuss their potential for achieving room-temperature superfluidity.
