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…
Emergent momentum-space topological pseudospin defects in non-Hermitian systems
Yow-Ming Robin Hu, Elena A. Ostrovskaya, Alexander Yakimenko +1
Topological defects are central to modern physics, from spintronics to photonics, due to their robustness and potential application in information processing. In this work, we disc…
Making ghost vortices visible in two-component Bose-Einstein condensates
Andrii Chaika, Andrea Richaud, Alexander Yakimenko
Ghost vortices constitute an elusive class of topological excitations in quantum fluids since the relevant phase singularities fall within regions where the superfluid density is a…
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…
Generation of Josephson vortices in stacked toroidal Bose-Einstein condensates
Nataliia Bazhan, Anton Svetlichny, Dominik Pfeiffer +3
Coupled coaxially stacked toroidal condensates with persistent currents suggest an appealing physical platform for the investigation of various phenomena related to interacting sup…
