Pancharatnam–Berry phase in condensate of indirect excitons

Geometric phases in matter are of fundamental interest. Here the authors observe the Pancharatnam–Berry phase in matter waves by imaging light interference patterns from cold gases of indirect excitons and find long-range coherent spin transport in the system.
