本文研究了具有随机磁场的线图上薛定谔算子的谱性质和输运性质。我们发现,它有一个纯的点谱指数衰减的特征函数的谱边缘,而出现的特征值与无限重,由于线图的结构。我们计算的电导率是零的频谱边缘,但非零和有限的孤立本征值上述。并对有关问题进行了讨论。
We study the spectral and transport properties of Schrodinger operators on line graphs with random magnetic fields. We show that it has a pure point spectrum with exponentially decaying eigenfunctions on spectral edges, whereas there appears an eigenvalue with infinite multiplicity due to the structure of line graphs. We compute the electrical conductivity which is zero on spectral edges, but is nonzero and finite on the isolated eigenvalue mentioned above. Some related problems are also discussed.
