Au approximate instantaneous eigenstate is presented for the many-spin system possessing the anisotropy exchange interaction in a strong magnetic field by the perturbation method.Based on the instantaneous eigenstate,...
The quantum phase of a moving dipole as it encircles an infinite line of magnetic charge,recently discovered by Wilkens(Phys.Rev.Lett.72(1994)5),is derived as a special case of Berry’s phase.
The Berry phase of spinor fields induced by gravity and inertia are studied starting with covariant Dirac equation in general relativity.The results obtained reveal the spin-gravity coupling effect explicitly.As examp...
