The fate of the resonating valence bond in graphene
Mariapia Marchi, Sam Azadi, Sandro Sorella
We apply a variational wave function capable of describing qualitatively and quantitatively the so called "resonating valence bond" in realistic materials, by improving standard ab…
Resonating valence bond wave function with molecular orbitals: Application to first-row molecules
M. Marchi, S. Azadi, M. Casula +1
We introduce a method for accurate quantum chemical calculations based on a simple variational wave function, defined by a single geminal that couples all the electrons into single…
A consistent description of the iron dimer spectrum with a correlated single-determinant wave function
Michele Casula, Mariapia Marchi, Sam Azadi +1
We study the iron dimer by using an accurate ansatz for quantum chemical calculations based on a simple variational wave function, defined by a single geminal expanded in molecular…
Pair distribution functions of the two-dimensional electron gas with two symmetric valleys
M. Marchi, S. De Palo, S. Moroni +1
We present component-resolved and total pair distribution functions for a 2DEG with two symmetric valleys. Our results are based on quantum Monte Carlo simulations performed at sev…
Correlation Energy and the Spin Susceptibility of the Two-Valley Two-dimensional Electron Gas
M. Marchi, S. De Palo, S. Moroni +1
We find that the spin susceptibility of a two-dimensional electron system with valley degeneracy does not grow critically at low densities, at variance with experimental results [A…
Pair-distribution functions of the two-dimensional electron gas
Paola Gori-Giorgi, Saverio Moroni, Giovanni B. Bachelet
Based on its known exact properties and a new set of extensive fixed-node reptation quantum Monte Carlo simulations (both with and without backflow correlations, which in this case…
