Breaking the curse of dimension for the electronic Schrödinger equation with functional analysis

Most approaches for solving the electronic Schrödinger equation do not fully exploit the functional-analytic simplicity of the electronic wavefunction. Because of this, the cost of these methods explodes exponentially with increasing electron number, an effect that is often called the curse of dimension. Recent work in mathematics and computer science shows how, by exploiting the smoothness of molecular wavefunctions, one can design methods …
