Second order self-energy of fermions with dipolar interaction — Jan Krieg1, •Philipp Lange1,2, and Peter Kopietz1,2 — 1Institut für Theoretische Physik, Universität Frankfurt, Frankfurt am Main, Germany — 2Department of Physics, University of Florida, Gainesville, Florida, USA
We calculate the self-energy, the quasiparticle residue and the effective mass of a two- and three-dimensional system of dipolar fermions, which are aligned by an external field, up to second order perturbation theory. The influence of the anisotropy of the dipolar interaction on these quantities is investigated as a function of the interaction strength and, for two-dimensional systems, the tilting angle between the external field and the normal of the plane of dipoles.
