波动Aharonov-Casher相位引起的退相干

Decoherence induced by a fluctuating Aharonov-Casher phase

Fernando C. Lombardo, Francisco D. Mazzitelli, Paula I. Villar

摘要:

研究了原子系统与经典电磁场耦合时的偶极子干涉。偶极子和经典场之间的相互作用诱导了一个随时间变化的Aharonov-Casher相位。在相位上求平均产生干涉图案中的条纹可见性的抑制。我们表明,在适当的实验条件下,偶极子的对比度损失是可以观察到的,几乎一样大的相干电子相应的。我们分析了不同的轨迹,以显示退相干因子与粒子的速度的依赖关系。

英文摘要:

Dipoles interference is studied when atomic systems are coupled to classical electromagnetic fields. The interaction between the dipoles and the classical fields induces a time-varying Aharonov-Casher phase. Averaging over the phase generates a suppression of fringe visibility in the interference pattern. We show that, for suitable experimental conditions, the loss of contrast for dipoles can be observable and almost as large as the corresponding one for coherent electrons. We analyze different trajectories in order to show the dependence of the decoherence factor with the velocity of the particles.
