Beyond single-reference fixed-node approximation in ab initio Diffusion Monte Carlo using antisymmetrized geminal power applied to systems with hundreds of electrons
Kousuke Nakano, Sandro Sorella, Dario Alfè +1
Diffusion Monte Carlo (DMC) is an exact technique to project out the ground state (GS) of a Hamiltonian. Since the GS is always bosonic, in fermionic systems the projection needs t…

How accurate are simulations and experiments for the lattice energies of molecular crystals?
Flaviano Della Pia, Andrea Zen, Dario Alfè +1
Molecular crystals play a central role in a wide range of scientific fields, including pharmaceuticals and organic semiconductor devices. However, they are challenging systems to m…
