我们报告了赝自旋进动对线性极化泵相干驱动的微谐振器中激子极化子集体运动的显着影响。特别是，我们证明六边形图案可以经历其极化的自发对称破缺，并在谐振器平面中开始匀速运动。与光学自旋霍尔效应类似，由于光子谐振腔模式的纵向-横向分裂（TE-TM分裂）引起的自旋轨道相互作用，这成为可能。我们推导出图案漂移速度的简单解析表达式。
We report on a remarkable effect of pseudospin precession on the collective motion of exciton-polaritons in a microresonator coherently driven by a linearly polarized pump. In particular, we show that hexagonal patterns can undergo a spontaneous symmetry breaking of their polarization and start a uniform motion in the plane of the resonator. Similar to the optical spin Hall effect, this becomes possible due to a spin-orbit interaction induced by a longitudinal-transverse splitting (TE-TM splitting) of the photonic resonator mode. We derive a simple analytical expression for the drift velocity of the patterns.
