# One-dimensional model of chiral fermions with Feshbach resonant interactions

@article{Prem2017OnedimensionalMO, title={One-dimensional model of chiral fermions with Feshbach resonant interactions}, author={Abhinav Prem and Victor Gurarie}, journal={arXiv: Quantum Gases}, year={2017}, pages={023111} }

We study a model of two species of one-dimensional linearly dispersing fermions interacting via an s-wave Feshbach resonance at zero temperature. While this model is known to be integrable, it possesses novel features that have not previously been investigated. Here, we present an exact solution based on the coordinate Bethe Ansatz. In the limit of infinite resonance strength, which we term the strongly interacting limit, the two species of fermions behave as free Fermi gases. In the limit of…

A one-dimensional gas of fermionic atoms interacting via an s-wave molecular Feshbach resonance exhibits a quantum phase transition from a phase in which the two superfluids are locked together to one in which, at low energies, quantum fluctuations suppress the Fesh Bach resonance (Josephson) coupling, effectively decoupling the molecular and atomic superfluids.
