Signatures of unconventional pairing in spin-imbalanced one-dimensional few-fermion systems
Daniel Pęcak, Tomasz Sowiński
Abstract
The authors show that the famous Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) correlations are present also in such an exotic system as one dimensional few body systems confined in a harmonic trap. This regime of parameters is far beyond homogeneous system in thermodynamic limit showing broad universality of this pairing mechanism. The work shows how the signatures of FFLO state can be measured using state-of-the-art experimental techniques.
