Spontaneous and engineered transformations of topological structures in nonlinear media with gain and loss
B. A. Kochetov, O. G. Chelpanova, V. R. Tuz +1
In contrast to conservative systems, in nonlinear media with gain and loss the dynamics of localized topological structures can exhibit unique features that can be controlled exter…
Spatiotemporal vortex rings in atomic Bose-Einstein condensates
O. G. Chelpanova, Y. I. Kuriatnikov, S. Vilchinskii +1
We investigate spatiotemporal vortex rings with phase dislocation both in space and time. It is demonstrated that these structures naturally appear as a periodical in time edge pha…
Analogues of Josephson junctions and black hole event horizons in atomic Bose-Einstein condensates
A. I. Yakimenko, O. I. Matsyshyn, A. O. Oliinyk +3
We study dynamical processes in coherently coupled atomic Bose-Einstein condensates. Josephson effects in ring-shaped and dumbbell geometries are theoretically investigated. Condit…
