Twisted superfluids in moving frame
arXiv:1912.07073
Abstract
Helical waveguide filled by superfluid is shown to transform rotations of the reference frame into linear displacements of the atomic ensemble and vise versa the linear displacements of the reference frame initialize rotations of ensemble. In the mean-field Gross-Pitaevskii equation with a weakly modulated gravitation potential the exact solutions for macroscopic wavefunction demonstrate the emergence of phase factor. For helical waveguides formed by phase-conjugated optical vortices with high angular momentum one may expect the significant improvement of the phase-sensitivity by factor containing compared to the conventional nonsingular matter-wave interferometry.
