Atomic dipoles motion in square vortex lattices trap.




Degenerate quantum gas in rotating helical trap.




Macroscopic wavefunction of the cold bosons in helical potential.



Red-detuned optical potential is formed
by two counter propagating Laguerre-Gaussian beams with opposite orbital angular momenta:
