Density-and-phase domain walls in a condensate with dynamical gauge potentials
Sayak Bhattacharjee, Roderich Moessner, Shovan Dutta
We show how one can generate domain walls that separate high- and low-density regions with opposite momenta in the ground state of a harmonically trapped Bose-Einstein condensate u…

Generating Symmetry-Protected Long-Range Entanglement in Many-Body Systems
Shovan Dutta, Stefan Kuhr, Nigel R. Cooper
Entanglement between spatially distant qubits is perhaps the most counterintuitive and vital resource for distributed quantum computing. However, despite a few special cases, there…
