We investigate non-reversible transient electron transport and non-adiabatic decay of resistance in non-ferromagnetic GeTe wires/thin films and find both directional hysteresis and offset of its minimum away from as a magnetic field is swept. Our study demonstrates interplay among Rashba spin-orbit coupling, Landau quantization and Zeeman splitting by employing quantum-Boltzmann equation and a non-adiabatic current. We further find non-reciprocal chemical potential fluctuations from quantum-capacitance coupling and show these extremely long-lived fluctuations decayed on the time scale of tens of milliseconds in the 1D case and over hundred seconds in the 2D case.

用于 Rashba-Landau 耦合低维 GeTe 系统中不可逆瞬态传输的量子 Boltzmann 方程
我们研究了非铁磁 GeTe 线/薄膜中电阻的不可逆瞬态电子传输和非绝热衰减,并发现其最小的方向滞后和偏移距 作为磁场 被扫。我们的研究通过使用量子-玻尔兹曼方程和非绝热电流证明了 Rashba 自旋轨道耦合、Landau 量子化和塞曼分裂之间的相互作用。我们进一步发现了来自量子电容耦合的非互易化学势波动,并表明这些极长寿命的波动在一维情况下以数十毫秒的时间尺度衰减,而在二维情况下则超过一百秒。
