Higher Order Hadronic Energy Level Shifts in Protonium
Xinwei Kong, Finn Ravndal
Using effective field theory for a proton and antiproton bound in a Coulomb potential, the shift of the ground state energy level is calculated to arbitrary order in the scattering…

What is the Regularized Casimir Vacuum Energy Density?
Xinwei Kong, Finn Ravndal
The regularized total Casimir energy in spacetimes with boundaries is not in general equal to the integral of the regularized energy density. This paradoxical phenomenon is most tr…
