Persistent currents in a strongly interacting multicomponent Bose gas on a ring

We consider a two-component Bose–Bose mixture at infinitely strong repulsive interactions in tightly confining, one-dimensional ring trap and subjected to an artificial gauge field. By employing the Bethe Ansatz exact solution for many-body wavefunction, we obtain ground state energy persistent currents up four particles. For each value of applied flux, then determine symmetry under particles exchange. find that ground-state display reduced periodicity with respect case non-interacting particles, corresponding reaching states fractional angular momentum per particle. relate this effect change Our results generalize ones previously reported fermionic mixtures both attractive highlight role effect.
