Zero-Variance Zero-Bias Principle for Observables in quantum Monte Carlo: Application to Forces
Roland Assaraf, Michel Caffarel
A simple and stable method for computing accurate expectation values of observable with Variational Monte Carlo (VMC) or Diffusion Monte Carlo (DMC) algorithms is presented. The ba…
Dynamical Symmetry Enlargement Versus Spin-Charge Decoupling in the One-Dimensional SU(4) Hubbard Model
R. Assaraf, P. Azaria, E. Boulat +2
We investigate dynamical symmetry enlargement in the half-filled SU(4) Hubbard chain using non-perturbative renormalization group and Quantum Monte Carlo techniques. A spectral gap…
Least-squares fitting approach using energy, gradient and Hessian data to obtain an accurate quartic force field : Application to H2O and H2CO
Philippe Carbonniere, Didier Begue, Alain Dargelos +1
In this work we present an attractive least-squares fitting procedure to obtain a quartic force field by using energy, gradient and Hessian data arising from electronic wave functi…
