非对易相空间的一种新表示

A new kind of representations on noncommutative phase space

Si-Cong Jing, Bing-Sheng Lin

摘要:

在非对易相空间中引入新的表示来表述量子力学,其中坐标-坐标和动量-动量都是非对易的。这些表述明确地显示了不同坐标和动量分量的自由度之间的纠缠特性。为了展示它们的潜在应用,我们在新的表象中导出了Wigner函数和Wigner算符的显式表达式,并精确求解了非对易相平面上同时存在动力学耦合和弹性耦合的二维谐振子.

英文摘要:

We introduce new representations to formulate quantum mechanics on noncommutative phase space, in which both coordinate-coordinate and momentum-momentum are noncommutative. These representations explicitly display entanglement properties between degrees of freedom of different coordinate and momentum components. To show their potential applications, we derive explicit expressions of Wigner function and Wigner operator in the new representations, as well as solve exactly a two-dimensional harmonic oscillator on the noncommutative phase plane with both kinetic coupling and elastic coupling.
