标题： Quantum Theory of Lee-Naughton-Lebed's Angular Effect in Strong Electric Fields

摘要： 一些时间以前，Kobayashi 等人 实验研究了所谓的 Lee-Naughton-Lebed（LNL）角度效应在强电场中 [K. Kobayashi, M. Saito, E. Omichi, and T. Osada, Phys. Rev. Lett. \textbf{96}, 126601 (2006)]。 他们发现强电场将$\alpha$-(ET)$_2$-基有机导体中的 LNL 电导率极大值分开，并假定引入了相应的电导率方程。 在本 信中，我们首次提出了中等强电场中 LNL 角度振荡的量子力学理论。 特别是，我们证明了我们得到的近似理论公式与假定的公式一致，并能很好地描述上述实验。 显示英文摘要

摘要： Some time ago, Kobayashi et al. experimentally studied the so-called Lee-Naughton-Lebed's (LNL) angular effect in strong electric fields [K. Kobayashi, M. Saito, E. Omichi, and T. Osada, Phys. Rev. Lett. \textbf{96}, 126601 (2006)]. They found that strong electric fields split the LNL conductivity maxima in $\alpha$-(ET)$_2$-based organic conductor and hypothetically introduced the corresponding equation for conductivity. In this Letter, for the first time we suggest quantum mechanical theory of the LNL angular oscillations in moderately strong electric fields. In particular, we demonstrate that the obtained by us approximate theoretical formula coincides with the hypothetical one and well describes the above mentioned experiments.
