摘要
以自旋非对易为背景,研究了三维各向同性谐振子.将非对易效应看作微扰项,得到了基态和第一激发态能级的二级修正和波函数的一级修正.在得到的波函数中发现了自旋非对易引入了位形自由度和自旋自由度的纠缠,这是对易空间中完全没有的新现象.
Under the influence of spin noncommutativity, we investigate the three-dimensional isotropic harmonic oscillator. Considering the noncommutative effect as perturbation, we obtain the second-order correction of energy and the first-order correction of wave-function on the ground state and the first excited state. In the obtained total wave-functions, we find that the effect of spin noncommutativity produces entanglement between the configuration space and spin space, which is a novel phenomenon that never appeared in the ordinary commutative space.
