非对易空间效应是一种在弦尺度下出现的物理效应.本文首先介绍了在Schwinger表象中角动量的3个分量用产生-消灭算符的表示形式,接着讨论了非对易相空间的量子力学代数;然后用对易空间谐振子的产生-消灭算符表示出了在非对易情况下的角动量;最后讨论了非对易相空间中角动量的分裂.
In the very tiny string scale, the effect of noncommutativity of space may appear. In this paper, the expression of angular momentum in Schwinger representation is briefly reviewed first, then the quantum mechanics algebra in noncommutative phase space is discussed, moreover, the angular momentum in noncommutative phase space is represented in terms of creation and annihilation operations of commutative space. At last, the angular momentum splitting effect is discussed in detail.
