Auxiliary Field Diffusion Monte Carlo calculations of magnetic moments of light nuclei from χEFT

We calculate the magnetic moments of light nuclei (A < 20) using the auxiliary field diffusion quantum Monte Carlo method with two- and three-nucleon forces from chiral effective field theory (χEFT) and consistent electromagnetic currents also obtained from χEFT. In addition to theoretical estimates for magnetic moments for a collection of light nuclei, we also present order-by-order estimates of the theoretical uncertainty stemming from the truncation of the chiral expansion for select nuclei.
