Approaching the Kosterlitz-Thouless transition for the classical XY model with tensor networks
Laurens Vanderstraeten, Bram Vanhecke, Andreas M. Laeuchli +1
We apply variational tensor-network methods for simulating the Kosterlitz-Thouless phase transition in the classical two-dimensional XY model. In particular, using uniform matrix p…
Large-scale numerical investigations of the antiferromagnetic Heisenberg icosidodecahedron
Joerg Ummethum, Juergen Schnack, Andreas M. Laeuchli
We present up to date investigations of the antiferromagnetic Heisenberg icosidodecahedron by means of the Density Matrix Renormalization Group method. We compare our results with…
Competition between two- and three-sublattice ordering for S=1 spins on the square lattice
Tamas A. Toth, Andreas M. Laeuchli, Frederic Mila +1
We provide strong evidence that the S=1 bilinear-biquadratic Heisenberg model with nearest-neighbor interactions on the square lattice possesses an extended three-sublattice phase…
Imbalanced thee-component Fermi gas with attractive interactions: Multiple FFLO-pairing, Bose-Fermi and Fermi-Fermi mixtures versus collapse and phase separation
Andreas Luscher, Andreas Laeuchli
We present a detailed study of the population imbalanced three-component Hubbard chain with attractive interactions. Such a system can be realized experimentally with three differe…
Approximate eigenvalue determination of geometrically frustrated magnetic molecules
R. Schnalle, A. Laeuchli, J. Schnack
Geometrically frustrated magnetic molecules have attracted a lot of interest in the field of molecular magnetism as well as frustrated Heisenberg antiferromagnets. In this article…
Dynamical Correlations of the Kagome S=1/2 Heisenberg Quantum Antiferromagnet
Andreas Laeuchli, Claire Lhuillier
We determine dynamical response functions of the S=1/2 Heisenberg quantum antiferromagnet on the kagome lattice based on large-scale exact diagonalizations combined with a continue…
