Classical Aspects of Quantum Walls in One Dimension
Tamas Fulop, Taksu Cheon, Izumi Tsutsui
We investigate the system of a particle moving on a half line x >= 0 under the general walls at x = 0 that are permitted quantum mechanically. These quantum walls, characterized by…

Spectral Structure of Quantum Line with a Defect
Taksu Cheon, Tamas Fulop, Izumi Tsutsui
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 th…

Moebius Structure of the Spectral Space of Schroedinger Operators with Point Interaction
Izumi Tsutsui, Tamas Fulop, Taksu Cheon
The Schroedinger operator with point interaction in one dimension has a U(2) family of self-adjoint extensions. We study the spectrum of the operator and show that (i) the spectrum…
