## Summary

Ab initio calculations of the structure and reactions of atomic nuclei are possible utilizing nuclear

lattice effective field theory. This method has been established as a new approach in theoretical

nuclear physics in the first two funding periods, as documented by the extended monograph on

“Nuclear Lattice Effective Field Theory - an Introduction”. In this funding period, we wish to address

the following issues: 1) to pin down the three-nucleon forces, 2) to understand the microscopic

origin of the spin-orbit interaction in atomic nuclei, 3) to achieve an understanding of the

microscopic origins of isospin I = 1 and isospin I = 0 pairing in nuclei, 4) to obtain a better

understanding of the essentials of nuclear binding, and 5) to perform simulations at non-zero

temperature and fixed particle number to study nuclear thermodynamics, in particular the phase

diagram of nuclear matter and dissociation of finite nuclei and the corresponding cluster yields in

nuclear collisions.
