Can you give some examples of vector precession equation dS/dz=ΩxS?

  1. Nov 10, 2012 #1
    Hi All,
    I know that vector precession equations such as mdV/dt=qBxV (Newton's Second Law written for the magnetic part of the Lorentz force) exist.
    In the last equation magnetic field B=(B1,B2,B3) acts as an effective torque and the speed V=(V1,V2,V3) is the “pseudo-spin vector”.
    These equations can be written also as:


    I know three applications of these equations:
    1) Optical Bloch equations written for two-level atom;
    2) Stokes equation of polarization optics;
    3) Gyroscope precession

    Can someone give other physical applications of the vector precession equation
