Physical dipoles and second order perturbation theory for dipolar fermions in two dimensions — •Philipp Lange, Jan Krieg, and Peter Kopietz — Institut für Theoretische Physik, Goethe-Universität Frankfurt, Max-von-Laue-Strasse 1, 60438 Frankfurt/Main, Germany

By considering electric physical dipoles, we propose a new regularization for the Fourier transform of the interaction of dipolar fermions in two dimensions. Using this regularization, we calculate the self-energy, the renormalized chemical potential, and the renormalized Fermi surface of dipolar fermions in two dimensions in full second order perturbation theory.
