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…
The antiferromagnetic spin-1/2 Heisenberg model on the square lattice in a magnetic field
Andreas Luscher, Andreas Laeuchli
We study the field dependence of the antiferromagnetic spin-1/2 Heisenberg model on the square lattice by means of exact diagonalizations. In a first part, we calculate the spin-wa…
The FFLO state in the one-dimensional attractive Hubbard model and its fingerprint in the spatial noise correlations
Andreas Luscher, Reinhard M. Noack, Andreas Laeuchli
We explore the pairing properties of the one-dimensional attractive Hubbard model in the presence of finite spin polarization. The correlation exponents for the most important fluc…
Spontaneous trimerization in a bilinear-biquadratic S=1 zig-zag chain
Philippe Corboz, Andreas M. Laeuchli, Keisuke Totsuka +1
Recent theoretical studies raised the possibility of a realization of spin nematic states in the S=1 triangular lattice compound NiGa_2S_4. We study the bilinear-biquadratic spin 1…
Spatial noise correlations of a chain of ultracold fermions - A numerical study
Andreas Luscher, Andreas Laeuchli, Reinhard M. Noack
We present a numerical study of noise correlations, i.e., density-density correlations in momentum space, in the extended fermionic Hubbard model in one dimension. In experiments w…
Plaquette bond order wave in the quarter-filled extended Hubbard model on the checkerboard lattice
Martin Indergand, Carsten Honerkamp, Andreas Laeuchli +2
An extended Hubbard model (including nearest-neighbor repulsion and antiferromagnetic spin exchange) is investigated on the frustrated checkerboard lattice, a two-dimensional analo…
