Quantitative estimates on the Hydrogen ground state energy in non-relativistic QED

Jean-Marie Barbaroux, Thomas Chen, Semjon Vugalter +1

In this paper, we determine the exact expression for the hydrogen binding energy in the Pauli-Fierz model up to the order $O({\alpha }^5\log {\alpha }^{-1})$, where $\alpha$ denotes the finestructure co…
