Discussion,en considering dynamics of quantum boson and spin systems, in the quasi classical region of parameters. There are several aspects of this problem. One aspect concerns the fundamental problem of correspondence between quantum and classical mechanics. This problem has existed sinse the creation of qua反复无常 发表于 2025-3-27 11:58:25

Perception and Bodily Dependencyson and spin CSs which will be widely used in the sections of that follow. In addition, we review the standard properties of boson and spin CSs, and then collect some identities and expressions that will be useful in discussing exact quantum dynamics of expectation values.Nostalgia 发表于 2025-3-28 02:59:06
,References no. 1 – 979 / ABD - ZUB,n 5.6). If chaotic dynamics appears in the classical limit of the system being considered, then in place of (1.1) we have . ∼ . · ln(.) (1.2), i.e., the time after which quantum corrections invalidate the classical description becomes much shorter than in the case (1.1).Ptosis 发表于 2025-3-28 08:05:53
