Abstract

Helical waveguide filled by superfluid is shown to transform rotations of the reference frame Ω\vec \Omega_{\oplus} into linear displacements of the atomic ensemble and vise versa the linear displacements of the reference frame V\vec V initialize rotations Ω\vec \Omega_{\oplus} of ensemble. In the mean-field Gross-Pitaevskii equation with a weakly modulated gravitation potential the exact solutions for macroscopic wavefunction Ψ\Psi demonstrate the emergence of redshiftredshift phase factor. For helical waveguides formed by phase-conjugated optical vortices with high angular momentum Lz=±±103÷4L_z=\pm \ell \hbar \sim \pm \hbar \cdot 10^{3 \div 4} one may expect the significant improvement of the phase-sensitivity δϕ\delta \phi by factor containing 22 \ell compared to the conventional nonsingular matter-wave interferometry.
