Nuclear Physics from Lattice QCD at Strong Coupling — •Wolfgang Unger — ETH Zürich

Understanding the properties of nuclear matter from first principles, starting from the QCD Lagrangian via lattice simulations, is one of the main goals of lattice QCD. Unfortunately this task is turned out to be too ambitious. However, in the limiting case of an infinite bare gauge coupling, this goal can be reached: the full phase diagram as a function of temperature and baryon chemical potential can be determined and also the nuclear potential can be obtained. I will present new results obtained from lattice QCD at strong coupling and explain in what respect this model describes some of the properties of nuclear matter, such as the origin of nuclear interactions.
