Spin effects in the particle current of Bose-Einstein condensates in synthetic gauge fields
The study investigates spin effects in particle current density within a synthetic Hall system using non-relativistic Bose-Einstein condensates with pseudospin-1/2 particles. It shows that the spin term in the current is crucial for matching classical drift velocity and affects circulation, leading to modified Aharonov-Bohm phase relationships. In interacting systems, this spin term manifests as edge currents even in vortex states.
