扶手椅型纳米管上的薛定谔算子。I

Schrödinger operators on armchair nanotubes. I

Andrey Badanin, Jochen Brüning, Evgeny Korotyaev, Igor Lobanov

摘要:

我们考虑了扶手椅型单壁纳米管的准一维模型上具有周期势的薛定谔算子。这个算子的谱由一个绝对连续的部分(间隔间隔)加上无限多个具有无限重数的本征值组成。我们用相同的本征值描述所有的本征函数。我们定义了一个李雅普诺夫函数,这是解析的一些黎曼曲面。在每一个薄片上,李雅普诺夫函数具有与标量情形相同的性质,但它有分支点,我们称之为共振。在例子中,我们显示了一些特定的潜在的真实和复杂的共振的存在。

英文摘要:

We consider the Schrödinger operator with a periodic potential on quasi-1D models of armchair single-wall nanotubes. The spectrum of this operator consists of an absolutely continuous part (intervals separated by gaps) plus an infinite number of eigenvalues with infinite multiplicity. We describe all eigenfunctions with the same eigenvalue. We define a Lyapunov function, which is analytic on some Riemann surface. On each sheet, the Lyapunov function has the same properties as in the scalar case, but it has branch points, which we call resonances. In example we show the existence of real and complex resonances for some specific potentials.
