Merging of vortices and antivortices in polariton superfluids
Merging of vortices and antivortices in polariton superfluids
Quantized vortices are remarkable manifestations on a macroscopic scale of the coherent nature of quantum fluids, and the study of their properties is of fundamental importance for the understanding of this peculiar state of matter. Cavity polaritons, due to their double light-matter nature, offer a unique controllable environment to investigate …
