The wavefunction matchingreplaces the short-distance part of the two-body wavefunction for a realistic interaction that exhibits strong oscillations with that of a simple, easily calculable interaction that shows no oscillations. The result is a new interaction that can be treated in quantum many-body calculations in perturbation theory.https://www.physik-astro.uni-bonn.de/en/news/internationales-forschungsteam-knackt-physik-nuss/meissner-publicity6.png/viewhttps://www.physik-astro.uni-bonn.de/en/news/internationales-forschungsteam-knackt-physik-nuss/meissner-publicity6.png/@@images/image-1200-bde1673d83f6da9f1f0e2757ffa59399.png
