The Resonating-Valence-Bond Ground State of Li Nanoclusters
D. Nissenbaum, L. Spanu, C. Attaccalite +2
We have performed Diffusion Quantum Monte Carlo simulations of Li clusters showing that Resonating-Valence-Bond (RVB) pairing correlations between electrons provide a substantial c…
Metal-insulator transition and strong-coupling spin liquid in the Hubbard model
Federico Becca, Luca F. Tocchio, Sandro Sorella
We study the phase diagram of the frustrated Hubbard model on the square lattice by using a novel variational wave function. Taking the clue from the backflow correl…
Local moments and magnetic order in the two-dimensional Anderson-Mott transition
Maria Elisabetta Pezzoli, Federico Becca, Michele Fabrizio +1
We study the role of electronic correlation in a disordered two-dimensional model by using a variational wave function that can interpolate between Anderson and Mott insulators. Wi…
Real-Time Diagrammatic Monte Carlo for Nonequilibrium Quantum Transport
Marco Schiro`, Michele Fabrizio
We propose a novel approach to nonequilibrium real-time dynamics of quantum impurities models coupled to biased non-interacting leads, such as those relevant to quantum transport i…
Two-level Physics in a Model Metallic Break Junction
P. Lucignano, G. E. Santoro, M. Fabrizio +1
We consider a model inspired by a metal break-junction hypothetically caught at its breaking point, where the non-adiabatic center-of-mass motion of the bridging atom can be treate…
Enhancement of thermal transport in the degenerate periodic Anderson model
V. Zlatić, R. Monnier, J. K. Freericks
The low-temperature transport coefficients of the degenerate periodic SU(N) Anderson model are calculated in the limit of infinite correlation between {\it f} electrons, within the…
