Robustness of discrete semifluxons in closed Bose–Hubbard chains
We present the properties of the ground state and low-energy excitations of Bose–Hubbard chains with a geometry that varies from open to closed and with a tunable twisted link. In the vicinity of the symmetric π -flux case the system behaves as an interacting gas of discrete semifluxons for finite c...
