Peculiarity of Symmetric Ring Systems with Double Y-Junctions and the magnetic effects
Yukihiro Fujimoto, Kohkichi Konno, Tomoaki Nagasawa
We discuss quantum dynamics in the ring systems with double Y-junctions in which two arms have same length. The node of a Y-junction can be parametrized by U(3). Considering mathem…
Quantum Reflection and Transmission in Ring Systems with Double Y-Junctions: Occurrence of Perfect Reflection
Yukihiro Fujimoto, Kohkichi Konno, Tomoaki Nagasawa +1
We consider the scattering problems of a quantum particle in a system with a single Y-junction and in ring systems with double Y-junctions. We provide new formalism for such quantu…
Resonant Transmission in One-Dimensional Quantum Mechanics with Two Independent Point Interactions: Full Parameter Analysis
Kohkichi Konno, Tomoaki Nagasawa, Rohta Takahashi
We discuss the scattering of a quantum particle by two independent successive point interactions in one dimension. The parameter space for two point interactions is given by $U(2)\…
Effects of Two Successive Parity-Invariant Point Interactions on One-Dimensional Quantum Transmission: Resonance Conditions for the Parameter Space
Kohkichi Konno, Tomoaki Nagasawa, Rohta Takahashi
We consider the scattering of a quantum particle by two independent, successive parity-invariant point interactions in one dimension. The parameter space for the two point interact…
