Two interacting hard disks within a circular cavity: towards a quantal equation of states
T. Kato, N. Nakazono, K. Nakamura
We investigate a circular cavity billiard within which a pair of identical hard disks of smaller but finite size is confined. Each disk shows a free motion except when bouncing ela…

Signature of Quantum Chaos in SQUID's
T. Kato, K. Tanimoto, K. Nakamura
Spectral statistics in band structures is studied in a realistic model describing superconducting quantum interference devices (SQUID's). By controlling an external magnetic flux,…

Cylindrical Domain Walls and Gravitational Waves -- Einstein Rosen wave emission from momentarily static initial configuration --
K. Nakamura, H. Ishihara
A self-gravitating cylindrical domain wall is considered as an example of non-spherical wall to clarify the interaction between a domain wall and gravitational waves. We consider t…
