论文摘要
Rotons可以存在于具有远距离相互作用的超速原子气中，也可以与自旋轨道耦合分散体存在。我们发现，在结合长距离相互作用和自旋轨道耦合的关节系统中共存了两种不同种类的rotons。一个罗顿起源于自旋轨道耦合，另外两个来自远程相互作用。它们的软化可以单独控制。我们发现的有趣的新现象是，自旋轨道耦合的旋转可以推动一个长距离互动roton的能量。自旋轨道耦合加速了该旋转的软化。自旋 - 轨道耦合辅助的旋转软化和不稳定性的后阶段被确定为超根。
Rotons can exist in ultracold atomic gases either with long-range interactions or with spin-orbitcoupled dispersions. We find that two different kinds of rotons coexist in a joint system combining long-range interactions and spin-orbit coupling. One roton originates from spin-orbit coupling and two others come from long-range interactions. Their softening can be controlled separately. The interesting new phenomenon which we find is that spin-orbit-coupled roton can push down the energy of one long-range-interaction roton. The spin-orbit coupling accelerates the softening of this roton. The post phase of spin-orbit-coupling-assisted roton softening and instability is identified as a superstripe.
