QMC Methods for Strongly Correlated Nuclear Systems

Quantum Monte Carlo (QMC) methods have become essential for investigating strongly correlated quantum systems across both condensed matter and nuclear physics. In the nuclear domain, these stochastic approaches provide high-fidelity ab-initio solutions of the many-body Schrödinger equation, enabling detailed predictions of the spectra, structure, and electroweak response of light nuclei, as well as the equation of state of nucleonic matter.

In this talk, I will discuss recent progress in applying QMC methods to light nuclei, with particular attention to advances in Variational Monte Carlo (VMC) and Green’s Function Monte Carlo (GFMC) for bound states and new developments for treating scattering states. I will highlight algorithmic improvements, scaling strategies, and advances in the treatment of realistic two- and three-nucleon interactions and consistent electroweak currents within these frameworks. Illustrative results using modern nuclear interactions will be presented and discussed.
