Vortices in Bose-Einstein condensates with $\mathcal{P}\mathcal{T}$-symmetric gain and loss

Lukas Schwarz, Holger Cartarius, Ziad H. Musslimani +2

We investigate vortex excitations in dilute Bose-Einstein condensates in the presence of complex $\mathcal{P}\mathcal{T}$-symmetric potentials. These complex potentials are used to describe…
