Random-exchange quantum Heisenberg antiferromagnets on the square lattice
Nicolas Laflorencie, Stefan Wessel, Andreas Laeuchli +1
The ground state properties of random-exchange spin-1/2 Heisenberg antiferromagnets on the square lattice are investigated using a combination of quantum Monte Carlo simulations, e…
Anomalous percolation and quantum criticality in diluted rare-earth nickelates
J. V. Alvarez, H. Rieger, A. Zheludev
A microscopic model for the diluted spin-mixed compounds (R_xY_(1-x))_2BaNiO_5 (R=magnetic rare-earth) is studied using Quantum Monte Carlo (QMC). The ordering temperature is shown…
Crossover effects in the random exchange spin-1/2 antiferromagnetic chain
Nicolas laflorencie, Heiko Rieger, Anders W. Sandvik +1
The random antiferromagnetic spin-1/2 XX and XXZ chain is studied numerically for varying strength of the disorder, using exact diagonalization and stochastic series expansion meth…
