Inferring rotations using a bosonic Josephson junction
Rhombik Roy, Ofir E. Alon
Rotation and quantum tunneling are fundamental concepts in physics, and their interplay in the ultracold atomic systems is of particular interest. In this theoretical work, we expl…
Dynamics and transport of Bose-Einstein condensates in bent potentials
Rhombik Roy, Ofir E Alon
The dynamics of bosons in curved geometries have recently attracted significant interest in quantum many-body physics. Leveraging recent experimental advances in tailored trapping…
Rotation quenches in trapped bosonic systems
Rhombik Roy, Sunayana Dutta, Ofir E. Alon
The ground state properties of strongly rotating bosons confined in an asymmetric anharmonic potential exhibit a split density distribution. However, the out-of-equilibrium dynamic…
Fragmentation of a trapped multiple-species bosonic mixture
O. E. Alon, L. S. Cederbaum
We consider a multiple-species mixture of interacting bosons, bosons of mass , bosons of mass , and bosons of mass in a harmonic trap of frequency…
Rotation-mediated bosonic Josephson junctions in position and momentum spaces
Sunayana Dutta, Ofir E. Alon
In ultracold atoms, bosons tunneling in a double-well potential can produce a typical Josephson junction in real space. A major advancement in quantum matter and simulations is ant…
Assessing small accelerations using a bosonic Josephson junction
Rhombik Roy, Ofir E. Alon
Bosonic Josephson junctions provide a versatile platform for exploring quantum tunneling and coherence phenomena in ultracold atomic systems. While extensive research has examined…
