Approach the fluctuation of eigenstates around the avoided level crossing by two-level dynamics
From level dynamics, we show that when two levels come to an avoided level crossing, violent fluctuations of the corresponding eigenstates are similar to a two level process: rapid mixing of the two eigenstate...

Gauge covariant construction of the coherent states for a time-dependent harmonic oscillator by algebraic dynamical method
Time-dependent coherent states for a time-dependent harmonic oscillator are constructed in the framework of algebraic dynamics. These coherent states are gauge-covariant, and its time evolution is governed onl...

New evidence for enhanced cosmogenic isotope production rate in the atmosphere ≈ 37 kaBP from the Guliya ice core
A36Cl peak was found in the predicted section of Guliya ice core, from the Qinghai-Tibetan Plateau, at about 37 kaBP. This cannot be interpreted by means of changes in the accumulation rate, but by the enhanced c...
