我们提出了一个理论模型，在该模型中，辐射诱导零电阻态的存在进行了分析。一个精确的解决方案，在辐射的存在下，谐振子波函数和弹性散射由于随机分布的带电杂质的微扰处理，形成我们的模型的基础。根据这个模型，大多数实验结果都被再现，包括电阻率振荡的形成、它们对辐射强度和频率的依赖性、温度效应以及电阻率最小值的位置。零电阻状态的存在，从而解释在电子微波驱动的轨道动力学和泡利不相容原理的相互作用。
We present a theoretical model in which the existence of radiation-induced zero-resistance states is analyzed. An exact solution for the harmonic oscillator wave function in the presence of radiation, and a perturbation treatment for elastic scattering due to randomly distributed charged impurities, form the foundations of our model. Following this model most experimental results are reproduced, including the formation of resistivity oscillations, their dependence on the intensity and frequency of the radiation, temperature effects, and the locations of the resistivity minima. The existence of zero-resistance states is thus explained in terms of the interplay of the electron microwave-driven orbit dynamics and the Pauli exclusion principle.
