The phase diagram of two-dimensional fast-rotating ultra-cold fermionic atoms near unitarity
摘要：
通过分析涡旋晶格，重入库珀配对和富尔德-费雷尔-拉金-奥夫钦尼科夫（FFLO）状态在一个单一的理论框架，我们探讨了如何涡旋和自旋纹理加入，以保护超导性对大磁场。我们使用一个快速旋转的超冷气体的费米原子附近的幺正性作为模型系统服从实验探索，并发现一个层次的自旋极化和FFLO阶段，其中金属或带绝缘体的未配对粒子共存的空间调制的超流体托管的涡旋晶格。量子涨落可以将这些相分别转化为强关联的“涡旋液体”金属和绝缘体。我们认为，涡旋晶格显着提高FFLO状态的稳定性，并讨论在冷原子实验中观察这些状态的前景。
英文摘要：
By analyzing vortex lattices, re-entrant Cooper pairing and Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) states in a single theoretical framework we explore how vortices and spin textures join to protect superconductivity against large magnetic fields. We use a rapidly rotating ultra-cold gas of fermionic atoms near unitarity as a model system amenable to experimental exploration, and discover a hierarchy of spin-polarized and FFLO phases in which a metal or a band-insulator of unpaired particles coexists with a spatially modulated superfluid hosting a vortex lattice. Quantum fluctuations can transform these phases into strongly correlated "vortex liquid" metals and insulators respectively. We argue that vortex lattices significantly enhance the stability of FFLO states and discuss prospects for observing these states in cold atom experiments.
