Using an original Quantum Monte Carlo algorithm, the authors studied the thermodynamical properties of a single hole in the two-dimensional infinite-U Hubbard model at finite temperature. They investigated the energy and the spin correlators as a function of an external orbital magnetic field. This field is found to destroy the Nagaoka ferromagnetism and to induce chirality in the spin background. The applied field is partially screened by a fictitious magnetic field coming from the chirality. The algorithm allows them to reach a temperature low enough to discuss the ground state properties of the model.
