Bose-Einstein condensation at finite momentum and magnon condensation in thin film ferromagnets
Johannes Hick, Francesca Sauli, Andreas Kreisel +1
We use the Gross-Pitaevskii equation to determine the spatial structure of the condensate density of interacting bosons whose energy dispersion epsilon_k has two degenerate minima…

Quantum Heisenberg antiferromagnets in a uniform magnetic field: nonanalytic magnetic field dependence of the magnon spectrum
Andreas Kreisel, Francesca Sauli, Nils Hasselmann +1
We reexamine the 1/S-correction to the self-energy of the gapless magnon of a D-dimensional quantum Heisenberg antiferromagnet in a uniform magnetic field h using a hybrid approach…

Low-density expansion for the two-dimensional electron gas
Francesca Sauli, Peter Kopietz
We show that in two dimensions (2D) a systematic expansion of the self-energy and the effective interaction of the dilute electron gas in powers of the two-body T-matrix T_0 can be…
