Persistent currents flowing in spatially closed tracks define one of the most iconic concepts in mesoscopic physics. They have been studied in solid-state platforms such as superfluids …
In this article, we provide perspectives for atomtronics circuits on quantum technology platforms beyond simple bosonic or fermionic cold atom matter-wave currents. Specifically …
We theoretically investigate the control of superfluid currents for ultracold gases confined in a ring lattice. The system is assumed to be in the presence of an artificial magnetic flux …

The one-dimensional Bose–Hubbard model in large-U limit has been studied via reducing and mapping the Hamiltonian to a simpler one. The eigenstates and eigenvalues have been …
