摘要：

Quantum Monte Carlo methods are powerful numerical tools to accurately solve the Schrodinger equation for nuclear systems, a necessary step to describe the structure and reactions of nuclei and nucleonic matter starting from realistic interactions and currents. Theseab-initiomethods have been used to accurately compute properties of light nuclei-including their spectra, moments, and transitions-and the equation of state of neutron and nuclear matter. In this work we review selected results obtained by combining quantum Monte Carlo methods and recent Hamiltonians constructed within chiral effective field theory.
