主　　题：rate Observation of tiny polarization rotation rate in total internal reflection via weak measurements 

摘      要：In this paper,we examine the tiny polarization rotation effect in total internal reflection due to the spin–orbit interaction of *** find that the tiny polarization rotation rate will induce a geometric phase gradient,which can be regarded as the physical origin of photonic spin Hall *** demonstrate that the spin-dependent splitting in position space is related to the polarization rotation in momentum space,while the spin-dependent splitting in momentum space is attributed to the polarization rotation in position ***,we introduce a quantum weak measurement to determine the tiny polarization rotation *** rotation rate in momentum space is obtained with 118 nm,which manifests itself as a spatial shift,and the rotation rate in position space is achieved with 38 μrad∕λ,which manifests itself as an angular *** investigation of the polarization rotation characteristics will provide insights into the photonic spin Hall effect and will enable us to better understand the spin–orbit interaction of light.
