Fragmentation and correlations in a rotating Bose-Einstein condensate undergoing breakup
Sunayana Dutta, Axel U. J. Lode, Ofir E. Alon
The theoretical investigation of rotating Bose-Einstein condensates has mainly focused on the emergence of quantum vortex states and the condensed properties of such systems. In th…
Dynamics of Ultracold Bosons in Artificial Gauge Fields: Angular Momentum, Fragmentation, and the Variance of Entropy
Axel U. J. Lode, Sunayana Dutta, Camille Lévêque
We consider the dynamics of two-dimensional interacting ultracold bosons triggered by suddenly switching on an artificial gauge field. The system is initialized in the ground state…
Dynamics of interacting bosons in a double well potential-harmonic versus chirp modulation
Sunayana Dutta, Pankaj Kumar Mishra, Budhaditya Chatterjee +1
We present effects of an external driving on the tunneling dynamics of interacting bosons confined in a double well potential. At large values of a periodic driving potential, the…
Management of the Correlations of Ultracold Bosons in Triple Wells
Sunayana Dutta, Marios C. Tsatsos, Saurabh Basu +1
Ultracold interacting atoms are an excellent tool to study correlation functions of many-body systems that are generally eluding detection and manipulation. Herein, we investigate…
Tunneling dynamics of correlated bosons in a double well potential
Sunayana Dutta, Apurba Barman, Anat Siddharth +2
The quantum dynamics of a few bosons in a double well potential is studied using a Bose Hubbard model. We consider both signs for the on-site interparticle interaction and also inv…
The Capture and Escape of Stars
J. L. Collett, S. N. Dutta, N. W. Evans
The shape of galaxies depends on their orbital populations. These populations change through capture into and escape from resonance. Capture problems fall into distinct cases depen…
