论文摘要
我们表明，具有任意边界的有限晶格可以支持大型退化子空间，这是由于晶格的基础翻译对称性所致。当晶格耦合到环境时，这些潜在的这些状态可能仍然与环境薄弱或完全脱离，从而在连续体中意识到了一种新型的结合状态。这些状态在晶格的特定方向上进行了强烈的定位，在与环境的强耦合方面，这会导致空间定位的次化状态。
We show that finite lattices with arbitrary boundaries may support large degenerate subspaces, stemming from the underlying translational symmetry of the lattice. When the lattice is coupled to an environment, a potentially large number of these states remains weakly or perfectly uncoupled from the environment, realising a new kind of bound states in the continuum. These states are strongly localized along particular directions of the lattice which, in the limit of strong coupling to the environment, leads to spatially-localized subradiant states.
