Antiferromagnetic character of the quantum phase transition in the Hubbard model on the honeycomb lattice Physical Review B (IF4.036), Pub Date : 2021-10-25, DOI: 10.1103/physrevb.104.155142 Johann Ostmeyer, Evan Berkowitz, Stefan Krieg, Timo A. Lähde, Thomas Luu, Carsten Urbach
We provide a unified, comprehensive treatment of all operators that contribute to the antiferromagnetic, ferromagnetic, and charge-density-wave structure factors and order parameters of the hexagonal Hubbard Model. We use the Hybrid Monte Carlo algorithm to perform a systematic, carefully controlled analysis in the temporal Trotter error and of the thermodynamic limit. We expect our findings to improve the consistency of Monte Carlo determinations of critical exponents. We perform a data collapse analysis and determine the critical exponent for the semimetal-Mott insulator transition in the hexagonal Hubbard Model. Our methods are applicable to a wide range of lattice theories of strongly correlated electrons.
