Quantum spacetime fluctuations: Lamb Shift and hyperfine structure of the hydrogen atom
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 Schroedinger 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. In addition, we analyze the corresponding Lamb shift effect
emerging from these fluctuations of spacetime. Once again, we will set a bound
to these oscillations resorting to the current experimental outcomesComment: 26 page
