离散量子相空间中的波包

Wave Packets in Discrete Quantum Phase Space

Jang Young Bang, Micheal S Berger

摘要:

研究了离散相空间的量子力学的性质。在连续极限下,找到了最小测不准态,这些态成为高斯波包。适当选择的哈密顿量,使自由粒子运动的连续极限,它被发现,完整或近似的周期性时间演化可以导致。这代表了波包复活的一个例子,在连续极限中,波包是人们熟悉的直线上的自由粒子运动。最后,我们研究了离散相空间的不确定原理,得到了连续相空间的修正项。

英文摘要:

The properties of quantum mechanics with a discrete phase space are studied. The minimum uncertainty states are found, and these states become the Gaussian wave packets in the continuum limit. With a suitably chosen Hamiltonian that gives free particle motion in the continuum limit, it is found that full or approximate periodic time evolution can result. This represents an example of revivals of wave packets that in the continuum limit is the familiar free particle motion on a line. Finally we examine the uncertainty principle for discrete phase space and obtain the correction terms to the continuum case.
