Thermodynamic properties of the Shastry-Sutherland model from quantum Monte Carlo simulations
Stefan Wessel, Ido Niesen, Jonas Stapmanns +4
We investigate the minus-sign problem that afflicts quantum Monte Carlo (QMC) simulations of frustrated quantum spin systems, focusing on spin S=1/2, two spatial dimensions, and th…

A ground state study of the spin-1 bilinear-biquadratic Heisenberg model on the triangular lattice using tensor networks
Ido Niesen, Philippe Corboz
Making use of infinite projected entangled pair states, we investigate the ground state phase diagram of the nearest-neighbor spin-1 bilinear-biquadratic Heisenberg model on the tr…
