AMPLITUDE DECOHERENCE OF HARMONIC OSCILLATOR IN FINITE-DIMENSIONAL HILBERT SPACE
有限维希尔伯空间谐振子的振幅消相干及其推广

To discuss the connection of the amplitude decoherenc e between a two state system and a harmonic o e of a harmonic oscillator in a finite dimensional Hilbert space and these systscillator,the amplitude decoherenc ems with uniform energy spectr there exit some differences between these systems in some respects,their amplituum are investigated.It is found that thought that de decoherence are quite similar due to the unif ormity of energy spectrum.
