      abstract     = {While first order perturbation theory is routinely used in
                      quantum Monte Carlo (QMC) calculations, higher-order terms
                      present significant numerical challenges. We present a new
                      approach for computing perturbative corrections in
                      projection QMC calculations. We demonstrate the method by
                      computing nuclear ground state energies up to second order
                      for a realistic chiral interaction. We calculate the binding
                      energies of several light nuclei up to 16O by expanding the
                      Hamiltonian around the Wigner SU(4) limit and find good
                      agreement with data. In contrast to the natural ordering of
                      the perturbative series, we find remarkably large second
                      order energy corrections. This occurs because the perturbing
                      interactions break the symmetries of the unperturbed
                      Hamiltonian. Our method is free from the sign problem and
                      can be applied to QMC calculations for many-body systems in
                      nuclear physics, condensed matter physics, ultracold atoms,
                      and quantum chemistry.},
