ABSTRACT:

The quantum wavefunction of the atomic nucleus is needed to understand nuclear reactions in stars and to decode the mass of the tiniest neutrinos. Such wavefunctions, which may have dozens or even hundreds of degrees of freedom, are a computational nightmare or a challenge. I will discuss how one approaches such a daunting task, with a focus on some of the important computational issues, and finish with a discussion of the state-of-the-art: ab initio calculations involving vectors with nearly a billion elements.
