Integrable models for asymmetric Fermi superfluids: Emergence of a new exotic pairing phase

J. Dukelsky, G. Ortiz, S. M. A. Rombouts +1

We introduce an exactly-solvable model to study the competition between the Larkin-Ovchinnikov-Fulde-Ferrell (LOFF) and breached-pair superfluid in strongly interacting ultracold a…
