论文摘要
我们表明,在具有典型不平衡和统一基态的超流体中,有稳定的孤子。这些溶液是由径向密度调制的形成,导致淋巴结。我们证明,这些孤子表现出非平凡的孤子 - 索顿和孤子涡流相互作用,并且可以以“孤子袋”的形式形成复杂的结合状态。在相位调节(fulde-ferrell)背景中,我们以稳定的涡流 - 抗反应对的形式找到了不同的孤子状态。
We show that in superfluids with fermionic imbalance and uniform ground state, there are stable solitons. These solutions are formed of radial density modulations resulting in nodal rings. We demonstrate that these solitons exhibit nontrivial soliton-soliton and soliton-vortex interactions and can form complicated bound states in the form of "soliton sacks". In a phase-modulating (Fulde-Ferrell) background, we find different solitonic states, in the form of stable vortex-antivortex pairs.
