Abstract: (EDP Sciences)

We present recent results for ^4He and ^6Li obtained with improved NN interactions derived from chiral effective field theory up to N^4LO. The many-body calculations are performed order-by-order in the chiral expansion. At N^3LO and N^4LO additional renormalization using the Similarity Renormalization Group is adopted to improve numerical convergence of the many-body calculations. We discuss results for the ground state energies, as well as the magnetic moment and the low-lying spectrum of ^6Li.
