Controllable high-speed polariton waves in a PT-symmetric lattice
Controllable high-speed polariton waves in a PT-symmetric lattice
Parity-time (PT) symmetry gives rise to unusual phenomena in many physical systems, presently attracting a lot of attention. One essential and non-trivial task is the fabrication and design of the PT-symmetric lattices in different systems. Here we introduce a method to realize such a lattice in an exciton-polariton condensate in …
