Jx. Zhu et al., NONADIABATIC GEOMETRIC PHASE IN A TEXTURED MESOSCOPIC RING SUBJECT TOA CROWN-LIKE MAGNETIC-FIELD, Zeitschrift fur Physik. B, Condensed matter, 102(2), 1997, pp. 153-155
With the aid of the exact solution for a quantum spin-1/2 in a rotatin
g magnetic held and by imposing a commensurability condition, we propo
se a novel experiment to test a kind of Aharonov-Anandan (AA) geometri
c phase in a textured mesoscopic ring subject to a crown-like magnetic
field.
