This week’s selected image comes from a recent Journal of Physics: Condensed Matter paper from Subhasree Pradhan. She used exact diagonalisation and Monte Carlo methods to compare spinless, interacting electrons on finite size triangular and square lattices, highlighting interplay between the applied magnetic field and electronic correlation.
