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…

The Striped Phase in Presence of Disorder and Lattice Potentials
N. Hasselmann, A. H. Castro Neto, C. Morais Smith +1
We study the influence of disorder and lattice effects on the striped phase and the incommensurate spin fluctuations of the cuprates and nickelates. Starting from a phenomenologica…
