Ising transition in the two-dimensional quantum Heisenberg model
Luca Capriotti, Tommaso Roscilde, Andrea Fubini +1
We study the thermodynamics of the spin- two-dimensional quantum Heisenberg antiferromagnet on the square lattice with nearest () and next-nearest () neighbor coupling…
Field-induced XY behavior in the S=1/2 antiferromagnet on the square lattice
Alessandro Cuccoli, Tommaso Roscilde, Ruggero Vaia +1
Making use of the quantum Monte Carlo method based on the worm algorithm, we study the thermodynamic behavior of the S=1/2 isotropic Heisenberg antiferromagnet on the square lattic…
Quantum Monte Carlo study of S=1/2 weakly-anisotropic antiferromagnets on the square lattice
Alessandro Cuccoli, Tommaso Roscilde, Valerio Tognetti +2
We study the finite-temperature behaviour of two-dimensional S=1/2 Heisenberg antiferromagnets with very weak easy-axis and easy-plane exchange anisotropies. By means of quantum Mo…
