Decoherence and the Branching of Chaos-less Classical Trajectory
Takuji Ishikawa
This study was started to know mysterious classicality of nuclei. This time, I found a new rule for decoherence. I used a model without chaos. As a result, it was shown that not on…

Decoherence in Sub-Systems of an Isolated System and the Disappearance of Quantum Multiverse
Takuji Ishikawa
This study was started to know mysterious classicality of nuclei. Using three particles model without external environments, it is found that decisions of respective state of three…

Study of Quantum Decoherence in a Finite System -- Three Schroedinger Cats and Crossing of Classical Orbits
Takuji Ishikawa
Nuclei are rather classical systems in a sense. In the old days, their phenomena were roughly explained in classical rules such as the liquid drop model. This fact may be understoo…
