如何探测波多尔斯基电动力学?

How can one probe Podolsky Electrodynamics?

R. R. Cuzinatto, C. A. M. de Melo, L. G. Medeiros, P. J. Pompeia

摘要:

我们探讨了检测波多尔斯基广义电动力学常数$a$的可能性。首先分析了B. Neyenhuis等人(Phys.Rev.Lett. 99,(2007)200401),他在Proca模型的背景下寻找与库仑平方反比定律的偏差。结果表明,本实验对$a$的测量精度不够。为了建立$a$的边界,我们研究了Podolsky静电势对氢原子基态的影响。氢原子的基态能量的值要求波多尔斯基常数小于5.6 fm,或者在大于35.51 MeV的能量标度中。

英文摘要:

We investigate the possibility of detecting the Podolsky generalized electrodynamics constant $a$. First we analyze an ion interferometry apparatus proposed by B. Neyenhuis, et al (Phys. Rev. Lett. 99, (2007) 200401) who looked for deviations from Coulomb's inverse-square law in the context of Proca model. Our results show that this experiment has not enough precision for measurements of $a$. In order to set up bounds for $a$ we investigate the influence of Podolsky's electrostatic potential on the ground state of the Hydrogen atom. The value of the ground state energy of the Hydrogen atom requires Podolsky's constant to be smaller than 5.6 fm, or in energy scales larger than 35.51 MeV.
