Abstrakt:

I will talk about two novel methods for electronic-structure calculations. The first is a deep-learning approach to quantum Monte Carlo, which provides highly accurate ground-state electronic wave functions and energies, and offers an alternative to the large and inefficient expansions in Slater determinants used in high-accuracy quantum chemistry. The second is a semi-empirical density-functional model of van der Waals interactions in molecules and materials that unifies many-body atomic approaches and nonlocal density functionals to offer a general, efficient, and accurate method.
