We present an overview of the extension of Nuclear Lattice Effective Field
Theory simulations to the regime of medium-mass nuclei. We focus on the
determination of the ground-state energies of the alpha nuclei 16O,
20Ne, 24Mg and 28Si by means of Euclidean time projection.Comment: 7 pages, 4 figures, presented at the 31st International Symposium on
Lattice Field Theory (LATTICE 2013), July 29 - August 3, 2013, Mainz, German
