连续介质中的体束缚态和表面束缚态

Bulk and surface bound states in the continuum

N. A. Gallo, M . I. Molina

摘要:

我们研究体和表面束缚态的连续(BIC),即平方可积,本地化模式嵌入在线性光谱带的离散晶格,包括相互作用的第一和第二近邻。我们提出了一种有效的方法来产生这样的模式和本地有界的潜力,支持BIC的基础上,开创性的维格纳-冯诺依曼的概念。结果表明,体和表面嵌入模式是结构稳定的,它们衰减速度比幂律在长距离的模式中心。

英文摘要:

We examine bulk and surface bound states in the continuum (BIC) that is, square-integrable, localized modes embedded in the linear spectral band of a discrete lattice including interactions to first-and second nearest neighbors. We suggest an efficient method for generating such modes and the local bounded potential that supports the BIC, based on the pioneering Wigner-von Neumann concept. It is shown that the bulk and surface embedded modes are structurally stable and that they decay faster than a power law at long distances from the mode center.
