Ultracold dipolar bosons trapped in atomtronic circuits

We consider a ring-shaped triple-well potential with few polar bosons with in-plane dipole orientation. By diagonalizing the extended Bose-Hubbard Hamiltonian, we investigate the ground-state properties of the system as we rotate the dipole angle and vary the on-site and dipole-dipole interaction st...
