非对易量子相空间中背景磁场中的谐振子

Harmonic oscillator in a background magnetic field in noncommutative quantum phase-space

Joseph Ben Geloun, Sunandan Gangopadhyay, Frederik G Scholtz

摘要:

在不使用任何形式的表象的情况下,我们在非对易相空间中显式求解了二维谐振子和背景磁场中的谐振子。一个关键的观察,我们做的是,对于一个特定的选择的非交换参数,时间反演对称性的系统得到恢复,因为能量谱变得简并。这与非对易位形空间相反,在非对易位形空间中,谐振子的时间反演对称性总是被破坏。

英文摘要:

We solve explicitly the two-dimensional harmonic oscillator and the harmonic oscillator in a background magnetic field in noncommutative phase-space without making use of any type of representation. A key observation that we make is that for a specific choice of the noncommutative parameters, the time reversal symmetry of the systems get restored since the energy spectrum becomes degenerate. This is in contrast to the noncommutative configuration space where the time reversal symmetry of the harmonic oscillator is always broken.
