Bound states, resonances, and their thermodynamic properties in pseudospin-1 systems with short-range impurities
E. V. Gorbar, Pavlo Sukhachov
Bound states and resonances induced by short-range impurities modeled by circular potential wells are analyzed in the vicinity of flat and dispersive bands in gapped and gapless ps…
Vortex State of Ultralight Dark Matter and the Fornax Timing Problem
V. Gorkavenko, O. Barabash, T. Gorkavenko +4
We investigate the impact of the vortex state of the ultralight dark matter (ULDM) on the dynamical friction acting on moving globular clusters. Comparing this force with that for…
Internal kinematics of dwarf galaxies orbitally moving in ultralight dark matter
E. V. Gorbar, A. I. Momot
For dwarf galaxies modeled as deformed Plummer spheres and orbitally moving in ultralight dark matter halo of the Milky Way, the torque induced by the dynamical friction force is d…
Nodal structure of bound-state wave functions for systems with quartic dispersion
E. V. Gorbar, B. E. Grinyuk, V. P. Gusynin
The nodal structure of bound-state wave functions for one-dimensional quantum systems with quartic energy-momentum dispersion and polynomial potentials is analysed by using the sem…
Damping of dynamical friction force in self-interacting ultralight dark matter and Fornax timing problem
E. V. Gorbar, O. V. Barabash, V. M. Gorkavenko +3
The dynamics of globular clusters in the Fornax dwarf galaxy pose a challenge for the standard cold dark matter and can be used to test other models of dark matter. We study this d…
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…
