Perturbative Renormalization in Quantum Mechanics
Cristina Manuel, Rolf Tarrach
Some quantum mechanical potentials, singular at short distances, lead to ultraviolet divergences when used in perturbation theory. Exactly as in quantum field theories, but much si…

Systematic Differential Renormalization to All Orders
J. I. Latorre, C. Manuel, X. Vilasis-Cardona
We present a systematic implementation of differential renormalization to all orders in perturbation theory. The method is applied to individual Feynamn graphs written in coordinat…
