Low-energy effects in brane worlds: Liennard-Wiechert potentials and Hydrogen Lamb shift

Hugo A. Morales-Técotl, Omar Pedraza, Luis O. Pimentel

Testing extra dimensions at low-energies may lead to interesting effects. In this work a test point charge is taken to move uniformly in the 3-dimensional subspace of a (3+$n$)-bra…
