摘要:

在高能物理中,坐标非对易性代表了空间本身可被量子化的核心思想,这一思想通过弦理论和非对易场论的框架得以表达。本文研究了这种非对易性对经历参数变化的二维量子振荡运动的影响。作为初步步骤,我们首先推导了具有时间无关参数的系统的量子解,其中考虑了坐标的非对易性。然后,我们基于非对易相空间形式论扩展研究,以获得具有时间相关参数的系统的相关解。由于参数随时间变化,我们聚焦的该系统是非定态的。在基本定态系统的量子处理中,我们利用了左右圆湮灭和产生算符;而对于非定态系统的薛定谔方程,我们使用Lewis-Riesenfeld不变量理论和与不变量相关的幺正变换过程来求解。我们的分析结果有助于从量子角度理解非对易性的影响,特别是结合参数变化的影响时。

英文摘要:

In high-energy physics, coordinate noncommutativity represents the core idea that space itself can be quantized, as expressed through the frameworks of string theory and noncommutative field theory. Influence of such a noncommutativity on 2D quantum oscillatory motion, which undergoes parameter variations, is investigated. We first derive quantum solutions of the system described with time-independent parameters considering the noncommutativity of coordinates as a preliminary step. And then, we extend our study, framed with noncommutative phase-space formalism, to obtain relevant solutions of the system with time-dependent parameters. This system, which we focus on, is nonstationary due to variation of parameters in time. While the left and right circular annihilation and creation operators are utilized in the quantal management of the basic stationary system, the Schrödinger equation of the nonstationary system is solved using the Lewis-Riesenfeld invariant theory and the invariant-related unitary transformation procedure. The outcome of our analysis is useful in understanding the effects of noncommutativity from quantum perspectives, especially in conjunction with the impact of parameter variations.
