由action变量导出的弱相对论谐振子的频率和能级

Frequencies and energy levels of the weakly relativistic harmonic oscillator from the action variable

M. K. Balasubramanya

摘要:

经典周期系统的频率和相应的量子系统的能级都可以通过作用量得到。我们证明了一维谐振子在经典、相对论和量子体系中作用量的两种形式的构造。相对论效应被认为是微扰的,在非相对论量子形式主义的背景下。在一个统一的框架下,说明了相对论量子系统向经典相对论和经典非相对论体系的转变。导出了弱相对论情形下经典相对论振子的频率和相应量子振子的能量本征值的计算公式。还研究了这些公式的非相对论和经典极限,这些公式一方面为相对论和非相对论系统之间的相似之处提供了有价值的见解,另一方面也为经典和量子系统之间的相似之处提供了有价值的见解。

英文摘要:

The frequency of a classical periodic system and the energy levels of the corresponding quantum system can both be obtained using action variables. We demonstrate the construction of two forms of the action variable for a one dimensional harmonic oscillator in classical, relativistic and quantum regimes. The relativistic effects are considered as perturbative, within the context of a non-relativistic quantum formalism. The transition of the relativistic quantum system to both classical relativistic and classical non-relativistic regimes is illustrated in a unified framework. Formulas for the frequency of a classical relativistic oscillator and the energy eigenvalues of the corresponding quantum oscillator for the weak relativistic case are derived. Also studied are the non-relativistic and classical limits of these formulas which provide valuable insights on the parallels between relativistic and non-relativistic systems on the one hand and between classical and quantum systems on the other.
