Scaling properties of the projected SO(5) model in three dimensions — •Martin Jöstingmeier1, Ansgar Dorneich1, Enrico Arrigoni1, Werner Hanke1, and Shou-Cheng Zhang2 — 1Institut für theoretische Physik, Am Hubland, D-97074 Würzburg — 2Department of Physics, Stanford University, Stanford, 94305 California
We study the scaling properties of the quantum projected SO(5) model in three dimensions by means of a highly accurate Quantum-Monte-Carlo analysis. Within the parameter regime studied (temperature and system size), we show that the scaling behavior is consistent with a SO(5)-symmetric critical behavior. We also show that possible departure away from the SO(5)-symmetric scaling occurs only in an quite narrow parameter regime, which is inaccessible both experimentally and numerically.
