Josephson spectroscopy in a circular atomic tunnel junction with acceleration-induced symmetry breaking
Yurii Borysenko, Yuriy Bidasyuk, Olena Prykhodko +5
We study Josephson dynamics in a long atomic Bose-Josephson junction formed by two tunnel-coupled coplanar Bose-Einstein-condensate rings. An in-plane linear acceleration breaks th…
Velocity dispersion profiles of dwarf spheroidal galaxies with self-interacting ultralight dark matter
K. Korshynska, E. V. Gorbar, Y. M. Bidasyuk +2
Dark-matter-dominated dwarf galaxies provide an excellent laboratory for testing dark matter models at small scale and, in particular, the ultralight dark matter (ULDM) class of mo…
Dynamical galactic effects induced by stable vortex structure in bosonic dark matter
K. Korshynska, Y. M. Bidasyuk, E. V. Gorbar +2
The nature of dark matter (DM) remains one of the unsolved mysteries of modern physics. An intriguing possibility is to assume that DM consists of ultralight bosonic particles in t…
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…
Fine structure of the stripe phase in ring-shaped Bose-Einstein condensates with spin-orbital-angular-momentum coupling
Y. M. Bidasyuk, K. S. Kovtunenko, O. O. Prikhodko
We report on a theoretical study of a ring-shaped Bose-Einstein condensate with Raman-induced spin-orbital-angular-momentum coupling. We analyze the structure of the ground-state o…
Symmetry breaking and phase transitions in Bose-Einstein condensates with spin-orbital-angular-momentum coupling
Y. Duan, Y. M. Bidasyuk, A. Surzhykov
Theoretical study is presented for a spinor Bose-Einstein condensate, whose two components are coupled by copropagating Raman beams with different orbital angular momenta. The inve…
