Systematic Study of the Hubbard Model in Finite Magnetic Field via Determinant Quantum Monte Carlo

ORAL

Abstract

Using determinant quantum Monte Carlo, we study the single-band Hubbard model in two dimensions, with electrons coupled to a constant out-of-plane magnetic field. We present thermodynamic, magnetic and transport properties of this model, including the local moment, compressibility, density of states, magnetoresistance, and hall conductivity, as a function of doping, temperature and Hubbard interaction strength. Our results are compared with experimental data, non-interacting and atomic limits, and other results obtained through alternative theoretical techniques.
