Nonclassical states in strongly correlated bosonic ring ladders
Nicolas Victorin, Tobias Haug, Leong-Chuan Kwek +2
We study the ground state of a bosonic ring ladder under a gauge flux in the vortex phase, corresponding to the case where the single-particle dispersion relation has two degenerat…
Topological pumping in Aharonov-Bohm rings
Tobias Haug, Rainer Dumke, Leong-Chuan Kwek +1
Topological Thouless pumping and Aharonov-Bohm effect are both fundamental effects enabled by the topological properties of the system. Here, we study both effects together: topolo…
Andreev-reflection and Aharonov-Bohm dynamics in atomtronic circuits
Tobias Haug, Rainer Dumke, Leong-Chuan Kwek +1
We study the quantum transport through two specific atomtronic circuits: a Y-junction and a ring-shaped condensate pierced by an effective magnetic flux. We demonstrate that for bo…
