Abstract
Feschbach resonances in a non-s-wave channel of two-component bosonic mixtures can induce atomic Bose-Einstein condensates with a nonzero orbital momentum in the optical lattice, if one component is in the Mott insulator state and the other is not. Such non-s-wave condensates break the symmetry of the lattice and, in some cases, time-reversal symmetry. They can be revealed in specific absorption imaging patterns.
摘要
在双组分玻色子混合物的非s波通道中的费什巴赫共振，能够在光晶格中诱导出具有非零轨道角动量的原子玻色 - 爱因斯坦凝聚体，前提是其中一个组分处于莫特绝缘态而另一个不是。这种非s波凝聚体会破坏晶格的对称性，并且在某些情况下会破坏时间反演对称性。它们可以在特定的吸收成像图案中显现出来。
