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…

Comparative Study of Indicators of Chaos in the Closed and Open Dicke Model
Prasad Pawar, Arpan Bhattacharyya, B. Prasanna Venkatesh
The Dicke model, renowned for its superradiant quantum phase transition, also exhibits a transition from regular to chaotic dynamics. In this work, we provide a systematic, compara…
