δ势一维(准)周期阵列中的精确电子态

Exact electron states in 1D (quasi-) periodic arrays of delta-potentials

Peter Kramer, Tobias Kramer

摘要:

计算和分析了吸引和排斥δ势的一维周期链和Fibonacci链有限部分的单电子本征态。Bloch边界条件和束缚态边界条件用传递矩阵表示。正能量和负能量的情景是有区别的。分析了势强度参数的依赖关系。计算散射矩阵。带芽在准周期链的解释的影响进行了讨论。

英文摘要:

Exact one-electron eigenstates in finite parts of 1D periodic and Fibonacci chains of attractive and repulsive delta potentials are computed and analyzed. Bloch and bound state boundary conditions are related in terms of transfer matrices. Scenarios of positive and negative energy are distinguished. The dependence on the potential strength parameter is analyzed. The scattering matrix is computed. Implications for the interpretation of band germs in quasiperiodic chains are discussed.
