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…
