Stable vortex in Bose-Einstein condensate dark matter
Y. O. Nikolaieva, A. O. Olashyn, Y. I. Kuriatnikov +2
The nature of dark matter (DM) is one of the most fascinating unresolved challenges of modern physics. One of the perspective hypotheses suggests that DM consists of ultralight bos…

Phase slips driven by acoustic waves in Bose-Einstein condensates with ring topology
Y. Kuriatnikov, A. Olashyn, A. I. Yakimenko
Rotational superradiance is one of the most fascinating phenomena in black-hole physics. Here, with the aim of probing quantum properties of superradiance in the lab, we investigat…

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…
