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…

Thermal Critical Points and Quantum Critical End Point in the Frustrated Bilayer Heisenberg Antiferromagnet
Jonas Stapmanns, Philippe Corboz, Frederic Mila +3
We consider the finite-temperature phase diagram of the frustrated Heisenberg bilayer. Although this two-dimensional system may show magnetic order only at zero temperatu…
