摘要

本文介绍了在邓克尔形式主义框架内对质量和频率随时间变化的一维和三维谐振子的研究,邓克尔形式主义是用邓克尔导数代替普通导数而构成的。为了确定波函数的一般形式,采用了 Lewis-Riesenfeld 方法。随后,考虑了时间中指数变化的质量函数,并在一维中推导出了依赖于奇偶性的量子相位、能量特征值和相应的波函数。研究结果表明,镜像对称性会影响波函数,从而影响相关概率。最后,研究扩展到三维情况,证明与径向方程的解一样,角方程的解也可以根据其镜像对称性进行分类。

Dunkl-Schrödinger Equation with Time-Dependent Harmonic Oscillator Potential

This paper presents an investigation into one- and three-dimensional harmonic oscillators with time-dependent mass and frequency, within the framework of the Dunkl formalism, which is constituted by replacing the ordinary derivative with the Dunkl derivative. To ascertain a general form of the wave functions the Lewis-Riesenfeld method was employed. Subsequently, an exponentially changing mass function in time was considered and the parity-dependent quantum phase, energy eigenvalues, and the corresponding wave functions were derived in one dimension. The findings revealed that the mirror symmetries affect the wave functions, thus the associated probabilities. Finally, the investigation was extended to the three-dimensional case, where it was demonstrated that, as with the solution of the radial equation, the solutions of the angular equation could be classified according to their mirror symmetries.

期刊介绍: International Journal of Theoretical Physics publishes original research and reviews in theoretical physics and neighboring fields. Dedicated to the unification of the latest physics research, this journal seeks to map the direction of future research by original work in traditional physics like general relativity, quantum theory with relativistic quantum field theory,as used in particle physics, and by fresh inquiry into quantum measurement theory, and other similarly fundamental areas, e.g. quantum geometry and quantum logic, etc.
