| Spectral Structure of Quantum Line with a Defect (2001) | |||||||||
Abstract | |||||||||
| We study the spectral properties of one-dimensional quantum wire with a single defect. We reveal the existence of the non-trivial topological structures in the spectral space of the system, which are behind the exotic quantum phenomena that have lately been found in the system..
