A quantum Monte Carlo algorithm for softcore boson systems
Jurij Smakov, Kenji Harada, Naoki Kawashima
An efficient Quantum Monte Carlo algorithm for the simulation of bosonic systems on a lattice in a grand canonical ensemble is proposed. It is based on the mapping of bosonic model…
Néel and Spin-Peierls ground states of two-dimensional SU(N) quantum antiferromagnets
Kenji Harada, Naoki Kawashima, Matthias Troyer
The two-dimensional SU(N) quantum antiferromagnet, a generalization of the quantum Heisenberg model, is investigated by quantum Monte Carlo simulations. The ground state for $N\le…
The Two-Dimensional S=1 Quantum Heisenberg Antiferromagnet at Finite Temperatures
Kenji Harada, Matthias Troyer, Naoki Kawashima
The temperature dependence of the correlation length, susceptibilities and the magnetic structure factor of the two-dimensional spin-1 square lattice quantum Heisenberg antiferroma…
