Signatures of the BCS-BEC crossover in the yrast spectra of Fermi quantum rings

Ulrich Ebling,

Abstract: We study properties of the lowest energy states at non-zero total momentum (yrast states) of the Hubbard model for spin-1 2 fermions in the quantum ring configuration with attractive on-site interaction at low density. In the one-dimensional (1D) case we solve the Hubbard model using the Bethe ansatz, while for the crossover into the 2D regime we use the Full-Configuration-Interaction Quantum Monte-Carlo method (FCIQMC) to obtain the yrast states for the spin-balanced Fermi system. We show how the yrast excita… Show more
