经典涨落场中自旋为1/2的Berry相位

Berry phase for a spin 1/2 in a classical fluctuating field

Gabriele De Chiara, G. Massimo Palma

摘要:

分析了经典控制参量的涨落对自旋1/2与周期性变化磁场相互作用系统Berry相的影响。它明确表明,在绝热极限失相是由于波动的动力学阶段。

英文摘要:

The effect of fluctuations in the classical control parameters on the Berry phase of a spin 1/2 interacting with a adiabatically cyclically varying magnetic field is analyzed. It is explicitly shown that in the adiabatic limit dephasing is due to fluctuations of the dynamical phase.
