捕捉zitterbewegung
Catching the zitterbewegung
摘要:
我们演示了如何zitterbewegung电荷振荡可以通过在三端结的电荷电导测量检测。通过调节自旋-轨道相互作用强度或外部磁场,可以调制zitterbewegung周期,转化为结的两个引出端中的互补电导振荡。所提出的实验装置是在所证明的技术和材料参数的范围内,并且能够观察到迄今为止难以捉摸的zitterbewegung现象。
英文摘要:
We demonstrate how the zitterbewegung charge oscillations can be detected through a charge conductance measurement in a three-terminal junction. By tuning the spin-orbit interaction strength or an external magnetic field the zitterbewegung period can be modulated, translating into complementary conductance oscillations in the two outgoing leads of the junction. The proposed experimental setup is within the reach of demonstrated technology and material parameters, and enables the observation of the so far elusive zitterbewegung phenomenon.
