论文摘要
我们证明了具有TE-TM自旋轨道耦合（SOC）的激子 - 波利顿量子流体中高角度动量湍流状态的形成。颗粒从准确的CW泵送\ SPL成分转移到\ SM成分的转移与通过不均匀性的量子涡流的湍流气体产生。我们表明，该系统在有限的波矢量上，由激光失谐控制在有限的波矢量上的形成不稳定。在有限大小的腔体中，带有该波矢量的域沿着腔的边界形成一个类似环的结构，中心的气体大多是同一符号涡流。 TE-TM SOC的符号，不稳定性的波矢量和空腔尺寸来施加总角动量。可以通过局部分散测量或通过干扰来实验检测此效果。因此，所提出的构型允许在连续泵浦的激子 - 果酱冷凝物中同时研究量子湍流和高角度动量状态。
We demonstrate the formation of a high angular momentum turbulent state in an exciton-polariton quantum fluid with TE-TM Spin-Orbit Coupling (SOC). The transfer of particles from quasi-resonantly cw pumped \spl component to \sm component is accompanied with the generation of a turbulent gas of quantum vortices by inhomogeneities. We show that this system is unstable with respect to the formation of bogolons at a finite wave vector, controlled by the laser detuning. In a finite-size cavity, the domains with this wave vector form a ring-like structure along the border of a cavity, with a gas of mostly same-sign vortices in the center. The total angular momentum is imposed by the sign of TE-TM SOC, the wave vector of instability, and the cavity size. This effect can be detected experimentally via local dispersion measurements or by interference. The proposed configuration thus allows simultaneous experimental studies of quantum turbulence and high-angular momentum states in continuously-pumped exciton-polariton condensates.
