Stable vortex structures in colliding self-gravitating Bose-Einstein condensates
Y. O. Nikolaieva, Y. M. Bidasyuk, K. Korshynska +3
A key feature of ultra-light dark matter composed by bosons is the formation of superfluid Bose-Einstein condensate (BEC) structures on galactic scales. We study collisions of BEC…
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…
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…
Solitons with rings and vortex rings on solitons in nonlocal nonlinear media
V. M. Biloshytskyi, A. O. Oliynyk, P. M. Kruglenko +2
Nonlocality is a key feature of many physical systems since it prevents a catastrophic collapse and a symmetry-breaking azimuthal instability of intense wave beams in a bulk self-f…
Stable bright solitons in two-component Bose-Einstein condensates
A. I. Yakimenko, K. O. Shchebetovska, S. I. Vilchinskii +1
Two-dimensional (2D) fundamental soliton-soliton pairs are investigated in binary mixtures of Bose-Einstein condensates with attractive interactions between atoms of the same type.…
Bright vector solitons in cross-defocusing nonlinear media
A. I. Yakimenko, O. O. Prikhodko, S. I. Vilchynskyi
We study two-dimensional soliton-soliton vector pairs in media with self-focusing nonlinearities and defocing cross-interactions. The general properties of the stationary states an…
