Spectral Properties of Three-Dimensional Quantum Billiards with a Pointlike Scatterer
T. Shigehara, Taksu Cheon
We examine the spectral properties of three-dimensional quantum billiards with a single pointlike scatterer inside. It is found that the spectrum shows chaotic (random-matrix-like)…
Resonance Tunneling in Double-Well Billiards with a Pointlike Scatterer
Taksu Cheon, T. Shigehara
The coherent tunneling phenomenon is investigated in rectangular billiards divided into two domains by a classically unclimbable potential barrier. We show that by placing a pointl…
Wave Chaos in Quantum Billiards with Small but Finite-Size Scatterer
T. Shigehara, Taksu Cheon
We study the low energy quantum spectra of two-dimensional rectangular billiards with a small but finite-size scatterer inside. We start by examining the spectral properties of bil…
Level spacing distribution of pseudointegrable billiard
T. Shigehara, N. Yoshinaga, Taksu Cheon +1
In this paper, we examine the level spacing distribution of the rectangular billiard with a single point-like scatterer, which is known as pseudointegrable. It is shown that…
Folded Bifurcation in Coupled Asymmetric Logistic Maps
Shoichi Midorikawa, Takayuki Kubo, Taksu Cheon
A system of coupled two logistic maps, one periodic and the other chaotic, is studied. It is found that with the variation of the coupling strength, the system displays several cur…
