Multiply Charged Vortex States of Polariton Condensates
Samuel N. Alperin, Natalia G. Berloff
The existence of quantized vortices is a key feature of Bose-Einstein condensates. In equilibrium condensates only quantum vortices of unit topological charge are stable, due to th…

Formation and Dynamics of Quantum Hydrodynamical Breathing Ring Solitons
Samuel N. Alperin, Natalia G. Berloff
We show that exciton-polariton condensates may exhibit a new fundamental, self-localized nonlinear excitation not seen in other quantum hydrodynamical systems, which takes the form…
