Simons Collaboration on the Many Electron Problem

Digital illustration of many electron problem

The Simons Collaboration on the Many Electron Problem brings together a group of scientists focused on developing new ways to solve the quantum mechanical behavior of systems comprised of many interacting electrons, with the goal of revolutionizing our ability to calculate and understand the properties of molecules and solids important in chemistry, physics and everyday life.
