Hydrodynamic theory of motion of quantized vortex rings in trapped superfluid gases
Lev P. Pitaevskii
I study vortex ring oscillations in a superfluid, trapped in an elongated trap, under the conditions of the Local Density Approximation. On the basis of the Hamiltonian formalism I…
Macroscopic theory of dark sector
Boris E. Meierovich
A simple Lagrangian with squared covariant divergence of a vector field as a kinetic term turned out an adequate tool for macroscopic description of the dark sector. The zero-mass…
Snake instability of dark solitons in fermionic superfluids
A. Cetoli, J. Brand, R. G. Scott +2
We present numerical calculations of the snake instability in a Fermi superfluid within the Bogoliubov-de Gennes theory of the BEC to BCS crossover using the random phase approxima…
ESR of the quasi-two-dimensional antiferromagnet with a triangular lattice CuCrO2
A. M. Vasiliev, L. A. Prozorova, L. E. Svistov +5
Using electron-spin-resonance (ESR) technique we investigate the magnetic structure of CuCrO2, quasi-two-dimensional antiferromagnet with weakly distorted triangular lattice. Reson…
Supercurrent and dynamical instability of spin-orbit-coupled ultracold Bose gases
Tomoki Ozawa, Lev P. Pitaevskii, Sandro Stringari
We investigate the stability of supercurrents in a Bose-Einstein condensate with one-dimensional spin-orbit and Raman couplings. The consequence of the lack of Galilean invariance…
Josephson Effect in Coherent Roton Aggregates
Lev A. Melnikovsky
A microwave electromagnetic field can excite a coherent roton aggregate in liquid helium around a dielectric resonator. We show that multiple coherent aggregates are excited simult…
