最小长度动量空间中的氢原子

Hydrogen atom in momentum space with a minimal length

Djamil Bouaziz, Nourredine Ferkous

摘要:

本文给出了具有广义测不准关系的氢原子问题的动量表象处理方法,它导致最小长度(Δ X_{i})_{min}= \hbar \sqrt(3β+ β ').我们证明了距离平方算子在λ ′ = 2β的情况下可以分解.我们解析地求解了s波的束缚态方程。由最小长度引起的对能谱的主要修正取决于\sqrt β。最小长度的上限约为10^{-9} fm。

英文摘要:

A momentum representation treatment of the hydrogen atom problem with a generalized uncertainty relation,which leads to a minimal length (ΔX_{i})_{min}= \hbar \sqrt(3β+β'), is presented. We show that the distance squared operator can be factorized in the case β'=2β. We analytically solve the s-wave bound-state equation. The leading correction to the energy spectrum caused by the minimal length depends on \sqrtβ. An upper bound for the minimal length is found to be about 10^{-9} fm.
