Fluctuations of spacetime and hyperfine structure of the hydrogen atom — •Ertan Göklü¹, Juan Israel Rivas², and Abel Camacho² — ¹ZARM-Universität Bremen, Am Fallturm, 28359 Bremen — ²Universidad Autónoma Metropolitana–Iztapalapa, Apartado Postal 55–534, C.P. 09340, México, D.F., México

We consider the consequences of the presence of metric fluctuations upon the properties of a hydrogen atom. Particularly, we introduce these metric fluctuations in the corresponding effective Schrödinger equation and deduce the modifications that they entail upon the hyperfine structure related to a hydrogen atom. We will find the change that these effects imply for the ground state energy of the system and obtain a bound for its size comparing our theoretical predictions against the experimental uncertainty reported in the literature.
