摘要：
The transport phenomena involving spin are instrumental in investigating quantum effects in many-body systems. In heavy-ion collisions, the recent measurement of spin polarization and spin alignment opens a new avenue to explore the quantum properties of hot and dense QCD matter. Based on linear response theory, we have systematically studied spin-momentum correlation induced by hydrodynamic forces. In addition to the widely studied thermal vorticity effects, we identify an undiscovered contribution from the fluid shear. This shear-induced polarization (SIP) can be viewed as the fluid analog of strain-induced polarization observed in elastic and nematic materials. I will explain the possible experimental evidence for SIP at RHIC and LHC.  Then, I will present our prediction for the signature of another long over-looked, namely,  Spin Hall effect induced by baryon chemical gradient at RHIC beam scan energies. I will conclude by a personal outlook for the future directions.
