Effective super Tonks-Girardeau gases as ground states of strongly attractive multicomponent fermions

Yin, Xiangguo; Guan, Xi-Wen; Batchelor, Murray; Chen, Shu

Description

In the strong interaction limit, attractive fermions with N-component hyperfine states in a one-dimensional waveguide form unbreakable bound cluster states. We demonstrate that the ground state of strongly attractive SU(N) Fermi gases can be effectively described by a super Tonks-Girardeau gaslike state composed of bosonic cluster states with strongly attractive cluster-cluster interaction for even N and a Fermi duality of a super Tonks-Girardeau gaslike state composed of fermionic cluster...[Show more]
