Trial function optimization for excited states of van der Waals clusters
M. P. Nightingale, Vilen Melik-Alaverdian
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 se…

Quantum Projector Method on Curved Manifolds
V. Melik-Alaverdian, G. Ortiz, N. E. Bonesteel
A generalized stochastic method for projecting out the ground state of the quantum many-body Schrödinger equation on curved manifolds is introduced. This random-walk method is of w…
