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…
