报告摘要:  

The supersolid phase characterized by superfluidity and long-range spatial periodicity of crystalline order is central to many branches of science ranging from condensed matter physics to ultracold atomic physics. First, I will focus on proposing a self-ordered checkerboard supersolid phase originating from dynamical spin-orbit coupling for a transversely pumped atomic Bose-Einstein condensate trapped in a ring cavity, corresponding to a superradiant anti-Tavis-Cummings phase transition. Subsequently, I will discuss our latest theoretical work on realizing spinor self-ordering superradiant phases resulting from cavity-mediated collective spin-squeezing interactions, exhibiting highly correlations in spin and momentum modes. Finally, I will provide a brief summary.
