Research Abstract

The original research proposal on BEC cosmology has been extended to much wider physics.
(1) coupled macro spin model for geomagnetic dynamics: Synchronization of the macro spins naturally yield geomagnetic reversal history.(2) origin of density fluctuations and the basics of quantum mechanics: We found that both of them have the common clue: causal dynamics during measurement.(3) Synchronization model for variable stars: We constructed a simple model for the pulsation of stars.(4) micro-macro correspondence in quantum theory: They are distinguished only by the tunneling time. (5) cosmological constant fine-tuning problem: We found the self organized criticality in the vacuum energy.
