Studies of systems with two fermionic bands (or equivalently, layers) with repulsive interaction strength U have a long history, with the periodic Anderson model (PAM) being one of the most frequently considered Hamiltonians. In this paper, we use qu

We investigate the magnetic properties of a heterostructure comprised of alternating metallic and Mott insulating layers of fermions with varying interlayer hybridization. Results from large-scale quantum Monte Carlo simulations at half-filling show

Experiments on cold atom systems in which a lattice potential is ramped up on a confined cloud have raised intriguing questions about how the temperature varies along isentropic curves, and how these curves intersect features in the phase diagram. In

We present Monte Carlo simulations of a generalization of the Feynman-Kikuchi model, which includes the possibility of vacancies and interactions between the particles undergoing exchange. By measuring the winding number (superfluid density) and dens

We study the ground state phases of Bose-Fermi mixtures in one-dimensional optical lattices with quantum Monte Carlo simulations using the Canonical Worm algorithm. Depending on the filling of bosons and fermions, and the on-site intra- and inter-spe
