摘要:

本文在非常狭义相对论(VSR)框架下研究了修正的狄拉克方程。进入低能区,得到非相对论性哈密顿量。事实证明,该哈密顿量类似于通过将旋量场耦合到洛伦兹破坏项而从标准模型扩展(SME)中获得的哈密顿量,但是从VSR的非局部特征继承了新的特征。此外,通过计算标准量子力学中的一阶能量修正,确定了VSR修正的Lorentz对称性对氢原子光谱的影响.其中的结果,我们强调,修改后的哈密顿量提供了非零的修正,解除简并的能级,并允许我们找到一个上限的VSR参数。

英文摘要:

In this work, we study the modified Dirac equation in the framework of very special relativity (VSR). The low-energy regime is accessed and the nonrelativistic Hamiltonian is obtained. It turns out that this Hamiltonian is similar to that achieved from the Standard Model Extension (SME) via coupling of the spinor field to a Lorentz-violating term, but new features arise inherited from the non-local character of the VSR. In addition, the implications of the VSR-modified Lorentz symmetry on the spectrum of a hydrogen atom are determined by calculating the first-order energy corrections in the context of standard quantum mechanics. Among the results, we highlight that the modified Hamiltonian provides non-vanishing corrections which lift the degeneracy of the energy levels and allow us to find an upper bound upon the VSR-parameter.
