The Semimetal-Antiferromagnetic Mott Insulator Quantum Phase Transition of the Hubbard Model on the Honeycomb Lattice
Johann Ostmeyer, Evan Berkowitz, Stefan Krieg +3
The Hubbard model on the honeycomb lattice undergoes a quantum phase transition from a semimetallic to a Mott insulating phase and from a disordered to an anti-ferromagnetically ph…
The Antiferromagnetic Character of the Quantum Phase Transition in the Hubbard Model on the Honeycomb Lattice
Johann Ostmeyer, Evan Berkowitz, Stefan Krieg +3
We provide a unified, comprehensive treatment of all operators that contribute to the anti-ferromagnetic, ferromagnetic, and charge-density-wave structure factors and order paramet…
The Semimetal-Mott Insulator Quantum Phase Transition of the Hubbard Model on the Honeycomb Lattice
Johann Ostmeyer, Evan Berkowitz, Stefan Krieg +3
We take advantage of recent improvements in the grand canonical Hybrid Monte Carlo algorithm, to perform a precision study of the single-particle gap in the hexagonal Hubbard model…
Accelerating Hybrid Monte Carlo simulations of the Hubbard model on the hexagonal lattice
Stefan Krieg, Thomas Luu, Johann Ostmeyer +2
We present different methods to increase the performance of Hybrid Monte Carlo simulations of the Hubbard model in two-dimensions. Our simulations concentrate on a hexagonal lattic…
