Nuclear Lattice Effective Field Theory (NLEFT) is a new method in the toolbox of theoretical nuclear physics.
After a short introduction into the foundations of NLEFT, the main part of this talk is devoted to the breaking and restoration of symmetries on a space-time lattice, especially rotational symmetry and Galilean invariance. The algorithm developed to deal with
the center-of-mass problem can also be used to study nuclear thermodynamics, and first results for nuclei at finite temperatures will be shown.
This seminar is organized within the ESNT workshop (13-17 May) about Symmetry breaking and symmetry preserving schemes.
