An Efficient Cluster Algorithm for CP(N-1) Models
B. B. Beard, M. Pepe, S. Riederer +1
We construct an efficient cluster algorithm for ferromagnetic SU(N)-symmetric quantum spin systems. Such systems provide a new regularization for CP(N-1) models in the framework of…

Quantum 2D Heisenberg antiferromagnet: bridging the gap between field-theoretical and semiclassical approaches
Bernard B. Beard, Alessandro Cuccoli, Ruggero Vaia +1
The field-theoretical result for the low- behaviour of the correlation length of the quantum Heisenberg antiferromagnet on the square lattice was recently improved by Hasenfratz…
