Chiral edge dynamics and quantum Hall physics in synthetic dimensions with an atomic erbium Bose-Einstein condensate

|
By Arif Warsi Laskar, Martin Weitz, Roberto Vittorio Roell, Franz Richard Huybrechts
| Physical Review B
Abstract Quantum Hall physics is at the heart of research on both matter and artificial systems, such as cold atomic gases, with nontrivial topological order. We report on the observation of a chiral edge current by transferring atomic wave packets simultaneously to opposite edges of a synthetic Hall system realized in the two-dimensional state space formed by one spatial and one synthetic dimension encoded in the J=6 electronic spin of erbium atoms.

Observation of Quantum Phase Synchronization in Spin-1 Atoms

|
By Arif Warsi Laskar, Pratik Adhikary, Suprodip Mondal, Parag Katiyar
| Physical Review B
Abstract With growing interest in quantum technologies, possibilities of synchronizing quantum systems have garnered significant recent attention. In experiments with dilute ensemble of laser cooled spin-1 Rb87 atoms, we observe phase difference of spin coherences to synchronize with phases of external classical fields. An initial limit-cycle state of a spin-1 atom localizes in phase space due to dark-state polaritons generated by classical two-photon tone fields.
