Peculiarities of the Motion of Spinning Particles in a Stationary Rotating Cosmological Model

The dynamics of particles described by the Dirac equation is considered in a homogeneous stationary rotating cosmological model, which is the closest generalization of Goedel’s cosmological model and admits the existence of unclosed timelike lines. It is shown that, in the space-time of the rotating cosmological model, the intrinsic angular momentum of a spinor particle precesses around the axis of rotation, and the angular velocity of rotation of the cosmological model affects the mass of the spinor particle, while the spin magnetic moment of the particles can generate electromagnetic radiation called “spin light.”
