Dynamical signatures of superfluidity and shear rigidity in different phases of a dipolar Bose-Einstein condensate

Soumyadeep Halder, Hari Sadhan Ghosh, Axel Pelster +1

We show that a sudden change in the polarization direction of the magnetic dipole moments of the atoms in a dipolar Bose-Einstein condensate (BEC) can serve as a useful dynamical p…
