Trial function optimization for excited states of van der Waals clusters
[chapter]
2002
Recent Advances in Quantum Monte Carlo Methods — Part II
A method is introduced to optimize excited state trial wave functions. The method is applied to ground and vibrationally excited states of bosonic van der Waals clusters of upto seven particles. Employing optimized trial wavefunctions with three-body correlations, we use correlation function Monte Carlo to estimate the corresponding excited state energies.
