Necklace Ansatz for strongly repulsive spin mixtures on a ring
Necklace Ansatz for strongly repulsive spin mixtures on a ring
We propose an alternative to the Bethe Ansatz method for strongly-interacting fermionic (or bosonic) mixtures on a ring. Starting from the knowledge of the solution for single-component non-interacting fermions (or strongly-interacting bosons), we explicitly impose periodic condition on the amplitudes of the spin configurations. This reduces drastically the number of …
