Adiabatic Preparation of a Heisenberg Antiferromagnet Using an Optical Superlattice
Michael Lubasch, Valentin Murg, Ulrich Schneider +2
We analyze the possibility to prepare a Heisenberg antiferromagnet with cold fermions in optical lattices, starting from a band insulator and adiabatically changing the lattice pot…

Modified spin-wave theory with ordering vector optimization I: frustrated bosons on the spatially anisotropic triangular lattice
Philipp Hauke, Tommaso Roscilde, Valentin Murg +2
We investigate a system of frustrated hardcore bosons, modeled by an XY antiferromagnet on the spatially anisotropic triangular lattice, using Takahashi's modified spin-wave (MSW)…
