摘要
Torsional optomechanics,which involves the transfer of angular mo-mentum from light to matter,has been a vibrant research area since Beth’s pioneering contribution in 1935.Beth proposed a method to measure the transfer of spin angular momentum using a torsional pen-dulum,1 laying the foundation for classical and quantum optomechanics related to particle levitation,trapping,and cooling in modern optics.
