Optimizing excited states in quantum Monte Carlo: A reassessment of double excitations
Stuart Shepard, Anthony Scemama, Saverio Moroni +1
Quantum Monte Carlo (QMC) methods have proven to be highly accurate for computing excited states, but the choice of optimization strategies for multiple states remains an active to…
Reproducibility of fixed-node diffusion Monte Carlo across diverse community codes: The case of water-methane dimer
Flaviano Della Pia, Benjamin X. Shi, Yasmine S. Al-Hamdani +30
Fixed-node diffusion quantum Monte Carlo (FN-DMC) is a widely-trusted many-body method for solving the Schrödinger equation, known for its reliable predictions of material and mole…
Shifting sands of hardware and software in exascale quantum mechanical simulations
Ravindra Shinde, Claudia Filippi, Anthony Scemama +1
The era of exascale computing presents both exciting opportunities and unique challenges for quantum mechanical simulations. Although the transition from petaflops to exascale comp…
Excited states with selected CI-QMC: chemically accurate excitation energies and geometries
Monika Dash, Jonas Feldt, Saverio Moroni +2
We employ quantum Monte Carlo to obtain chemically accurate vertical and adiabatic excitation energies, and equilibrium excited-state structures for the small, yet challenging, for…
Quantum Package 2.0: An Open-Source Determinant-Driven Suite of Programs
Yann Garniron, Thomas Applencourt, Kevin Gasperich +16
\textsc{Quantum Package} is an open-source programming environment for quantum chemistry specially designed for wave function methods. Its main goal is the development of determina…
