Physics of singular points in quantum mechanics
Izumi Tsutsui, Tamas Fulop
Defects or junctions in materials serve as a source of interactions for particles, and in idealized limits they may be treated as singular points yielding contact interactions. In…

Quantum force due to distinct boundary conditions
Tamas Fulop, Hitoshi Miyazaki, Izumi Tsutsui
We calculate the quantum statistical force acting on a partition wall that divides a one dimensional box into two halves. The two half boxes contain the same (fixed) number of noni…

Spectral properties on a circle with a singularity
Tamas Fulop, Izumi Tsutsui, Taksu Cheon
We investigate the spectral and symmetry properties of a quantum particle moving on a circle with a pointlike singularity (or point interaction). We find that, within the U(2) fami…
