On the Generalized Bloch Precession Equations
arXiv:1302.4923 · doi:10.1088/1367-2630/16/5/053050
Abstract
The Bloch equations, which describe spin precession and relaxation in external magnetic fields, can be generalized to include the evolution of polarization tensors of various ranks in arbitrary multipole fields. The derivation of these generalized Bloch equations can be considerably simplified by using a particular bra-ket notation for irreducible tensors.
