We investigate the two-dimensional Hubbard model on the planar pyrochlore lattice at half filling. By means of variational Monte Carlo simulations including nearest neighbor doublon-holon correlations as well as onsite correlations, we discuss how the semi-metallic state is stabilized at zero temper
