Evolution of the Fermi Surface across a Magnetic Order-Disorder Transition in the Two-Dimensional Kondo Lattice Model: A Dynamical Cluster Approach
L. C. Martin, F. F. Assaad
We use the dynamical cluster approximation, with a quantum Monte Carlo cluster solver on clusters of up to 16 orbitals, to investigate the evolution of the Fermi surface across the…
Dynamical dimer correlations at bipartite and non-bipartite Rokhsar-Kivelson points
A. Laeuchli, S. Capponi, F. F. Assaad
We determine the dynamical dimer correlation functions of quantum dimer models at the Rokhsar-Kivelson point on the bipartite square and cubic lattices and the non-bipartite triang…
Systematic errors in Gaussian Quantum Monte Carlo and a systematic study of the symmetry projection method
P. Corboz, A. Kleine, F. F. Assaad +3
Gaussian Quantum Monte Carlo (GQMC) is a stochastic phase space method for fermions with positive weights. In the example of the Hubbard model close to half filling it fails to rep…
Spin gap and string order parameter in the ferromagnetic Spiral Staircase Heisenberg Ladder: a quantum Monte Carlo study
C. Brünger, F. F. Assaad, S. Capponi +3
We consider a spin-1/2 ladder with a ferromagnetic rung coupling J_\perp and inequivalent chains. This model is obtained by a twist (θ) deformation of the ladder and interpolates b…
Diagrammatic Determinantal methods: projective schemes and applications to the Hubbard-Holstein model
F. F. Assaad, T. C. Lang
We extend the weak-coupling diagrammatic determinantal algorithm to projective schemes as well as to the inclusion of phonon degrees of freedom. The projective approach provides a…
