Spin relaxation with bistable precession

Physical Review A, 1991
We study the effects of the reaction field on the spin relaxation. We find that they are not only responsible for a nonlinear friction process, as recently pointed out by several authors, but, in the case of sufficiently strong coupling, they also result in a bistable precession process.

Simulations of Precessing Jets

2003
We report on the results of a three-dimensional, relativistic, hydrodynamical simulation of a precessing jet through which a compact blob of matter is set to propagate. We conclude that the morphology of superluminal sources is the result of a complex combination of phase motions, viewing angle selection effects, and non-linear interactions between ...

Photometry of Precessing Torses

Journal of the Optical Society of America, 1966
The photometry of the flux received from a rotating, reflecting surface is developed. In cases where Lambert’s law of diffuse reflection holds, a self-conjugate photometric dyadic can be defined, which determines the received flux when the unit vector to the observer and the unit-vector to the source of collimated flux incident on the reflecting ...

Merons and Thomas Precession

Physical Review Letters, 1996
In a recent study of Thomas precession of electron spin in the context of the Dirac equation, Shankar and Mathur identify the non-Abelian Berry potential (arising from Kramers degeneracy) with the meron. We point out that there is a global mathematical subtlety which prevents such an identification.
