Spin Response to Localized Pumps: Exciton Polaritons Versus Electrons and Holes

Vincent Sacksteder, A. A. Pervishko, I. A. Shelykh

Polariton polarization can be described in terms of a pseudospin which can be oriented along the $x,y,$ or $z$ axis, similarly to electron and hole spin. Unlike electrons and hol…
