论文摘要
我们研究了通过旋转轨道偶联诱导的参数共振产生的法拉第模式，并在旋转玻璃体凝结物中与排斥相互作用产生。 Bose-Einstein冷凝物的集体基本激发，包括密度波和自旋波，是由于拉曼诱导的自旋轨道耦合而导致的，以及两个拉曼激光器的相对相位的淬灭，而没有任何系统参数的调节。我们在驱动频率的整数倍数处观察到几种较高的参数共振舌，并研究了法拉第不稳定性和调制不稳定性之间的相互作用，当我们淬灭自旋轨道耦合的Bose-Einstein冷凝物从零孔相对于平面波相。如果失呼等于零，则组合共振的波数几乎不会随着自旋轨道耦合的强度增加而变化。如果淬火后的失呼不等于零，则单个组合共振舌头将分为两部分。
We study the Faraday patterns generated by spin-orbit-coupling induced parametric resonance in a spinor Bose-Einstein condensate with repulsive interaction. The collective elementary excitations of the Bose-Einstein condensate, including density waves and spin waves, are coupled as the result of the Raman-induced spin-orbit coupling and a quench of the relative phase of two Raman lasers without the modulation of any of the system's parameters. We observed several higher parametric resonance tongues at integer multiples of the driving frequency and investigated the interplay between Faraday instabilities and modulation instabilities when we quench the spin-orbit-coupled Bose-Einstein condensate from zero-momentum phase to plane-wave phase. If the detuning is equal to zero, the wave number of combination resonance barely changes as the strength of spin-orbit coupling increases. If the detuning is not equal to zero after a quench, a single combination resonance tongue will split into two parts.
