一维准周期镶嵌模型的扩展态
摘要
Abstract
Recent theoretical studies have found that there is a mobility edge in the one-dimensional quasi-periodic mosaic model.This paper studies the quantum transport of the model,especially the two-port conductance of the extended state,its trans-port phase diagram,average value and statistical distribution.The conductance of the extended state is not always 1,but there are interference resonance fringes.We explain these interference fringes by the behavior of wave function.The extended state of the model can survive under extremely strong quasi-periodic potential energy.Explain the physical images through the statistical distri-bution of conductance and the comparison with the fractal dimension of wave function.关键词
