Properties of 4He and 6Li with improved chiral EFT interactions

We present recent results for 4 He and 6 Li obtained with improved NN interactions derived from chiral effective field theory up to N 4 LO. The many-body calculations are performed order-by-order in the chiral expansion. At N 3 LO and N 4 LO 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 6 Li.
