s- and p-superfluidity of Fermi atoms in Bose-Fermi mixtures
E. V. Gorbar, Y. O. Nikolaieva, I. V. Oleinikova +2
The p-wave superfluid is characterized by nontrivial topological characteristics essential for fault-tolerant quantum state manipulation. However, the practical realization of the…
Spatiotemporal vortex rings in atomic Bose-Einstein condensates
O. G. Chelpanova, Y. I. Kuriatnikov, S. Vilchinskii +1
We investigate spatiotemporal vortex rings with phase dislocation both in space and time. It is demonstrated that these structures naturally appear as a periodical in time edge pha…
p-wave superfluidity in mixtures of ultracold Fermi and spinor Bose gases
O. Y. Matsyshyn, A. I. Yakimenko, E. V. Gorbar +2
We reveal that the p-wave superfluid can be realized in a mixture of fermionic and F=1 bosonic gases. We derive a general set of the gap equations for gaps in the s- and p-channels…
Stochastic phase slips in toroidal Bose-Einstein condensates
Kyrylo Snizhko, Karyna Isaieva, Yevhenii Kuriatnikov +3
Motivated by recent experiments we study the influence of thermal noise on the phase slips in toroidal Bose-Einstein condensates with a rotating weak link. We derive a generalized…
Stable Hopf solitons in rotating Bose-Einstein condensates
Y. M. Bidasyuk, A. V. Chumachenko, O. O. Prikhodko +3
We reveal that Hopf solitons can be stabilized in rotating atomic Bose-Einstein condensate. The Hopfion is a matter-wave vortex complex which carries two independent winding number…
Generation and decay of persistent current in a toroidal Bose-Einstein condensate
A. I. Yakimenko, S. I. Vilchinskii, Y. M. Bidasyuk +3
Persistent current, or "flow without friction", as well as quantum vortices are the hallmarks of superfluidity. Recently a very long-lived persistent flow of atoms has been experim…
Vortices in a toroidal Bose-Einstein condensate with a rotating weak link
A. I. Yakimenko, Y. M. Bidasyuk, M. Weyrauch +2
Motivated by a recent experiment [K.C. Wright et. al. Phys. Rev. Lett. 110, 025302 (2013)], we investigate deterministic discontinuous jumps between quantized circulation states in…
Vortex excitation in a stirred toroidal Bose-Einstein condensate
A. I. Yakimenko, K. O. Isaieva, S. I. Vilchinskii +1
Motivated by the recent experiment [Wright et al., Phys. Rev. A 88, 063633 (2013)], we investigate formation of vortices in an annular BEC stirred by a narrow blue-detuned optical…
Stability of persistent currents in spinor Bose-Einstein condensates
A. I. Yakimenko, K. O. Isaieva, S. I. Vilchinskii +1
Motivated by a recent experiment [S. Beattie, S. Moulder, R. J. Fletcher, and Z. Hadzibabic, PRL 110, 025301 (2013)] we study the superflow of atomic spinor Bose-Einstein condensat…
