Superfluid transition of the second layer of He-4 on graphite: does substrate corrugation matter?
Massimo Boninsegni, Saverio Moroni
The second layer of He-4 adsorbed on a graphite substrate is studied by Quantum Monte Carlo simulations. We make use of a microscopic model of the substrate fully accounting for it…
Double excitation energies from quantum Monte Carlo using state-specific energy optimization
Stuart Shepard, Ramón Lorenzo Panadés-Barrueta, Saverio Moroni +2
We show that recently developed quantum Monte Carlo methods, which provide accurate vertical transition energies for single excitations, also successfully treat double excitations.…
Quadriexcitons and excitonic condensate in a symmetric electron-hole bilayer with valley degeneracy
Stefania De Palo, F. Tramonto, Saverio Moroni +1
Using quantum Monte Carlo simulations we have mapped out the zero temperature phase diagram of a symmetric electron-hole bilayer with twofold valley degeneracy, as function of the…
Wave function Ansatz (but Periodic) Networks and the Homogeneous Electron Gas
Max Wilson, Saverio Moroni, Markus Holzmann +4
We design a neural network Ansatz for variationally finding the ground-state wave function of the Homogeneous Electron Gas, a fundamental model in the physics of extended systems o…
Reference excitation energies of increasingly large molecules: a QMC study of cyanine dyes
Alice Cuzzocrea, Saverio Moroni, Anthony Scemama +1
We revisit here the lowest vertical excitations of cyanine dyes using quantum Monte Carlo and leverage on recent developments to systematically improve on previous results. In part…
Energy derivatives in real-space diffusion Monte Carlo
Jesse van Rhijn, Claudia Filippi, Stefania De Palo +1
We present unbiased, finite--variance estimators of energy derivatives for real--space diffusion Monte Carlo calculations within the fixed--node approximation. The derivative $d_λE…
