Deciphering the coalescence behavior of Coulomb-Schrödinger atomic wave functions from an operator product expansion
Yingsheng Huang, Yu Jia, Rui Yu
We revisit the coalescence behavior of the atomic Schrödinger wave functions from the angle of an operator product expansion (OPE) within the nonrelativistic Coulomb-Schrödinger…

A tale of Bethe logarithms: leptonic widths of and Lamb shift
Yu Jia, Jichen Pan
The rare annihilation decays of -wave spin-triplet quarkonia into lepton pair have to proceed via two-photon intermediate state, which are plagued with the infrared divergence s…
