  • Title: Rotation of transparent, nonbirefringent objects by transfer of the spin angular momentum of light.
    Author: Dasgupta R, Gupta PK.
    Journal: Opt Lett; 2005 Feb 15; 30(4):394-6. PubMed ID: 15762439.
    Abstract:
    The transfer of the spin angular momentum of light to small objects has been discussed only for absorbing or birefringent objects. However, we show that it can also be transferred to objects that are nonabsorbing and nonbirefringent. Our estimate of the magnitude of the spin angular momentum transferred to a transparent, nonbirefringent sodium bromate crystal predicts rotational speeds in reasonable agreement with experimental results.
