Chaos, Metastability and Ergodicity in Bose-Hubbard Superfluid Circuits
Geva Arwas, Doron Cohen
The hallmark of superfluidity is the appearance of metastable flow-states that carry a persistent circulating current. Considering Bose-Hubbard superfluid rings, we clarify the rol…

Resonant persistent currents for ultracold bosons on a lattice ring
Geva Arwas, Doron Cohen, Frank Hekking +1
We consider a one-dimensional bosonic gas on a ring lattice, in the presence of a localized barrier, and under the effect of an artificial gauge field. By means of exact diagonaliz…

Superfluidity in Bose-Hubbard circuits
Geva Arwas, Doron Cohen
A semiclassical theory is provided for the metastability regime-diagram of atomtronic superfluid circuits. Such circuits typically exhibit high-dimensional chaos; and non-linear re…
