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…
Optimization of ground and excited state wavefunctions and van der Waals clusters
M. P. Nightingale, Vilen Melik-Alaverdian
A quantum Monte Carlo method is introduced to optimize excited state trial wavefunctions. The method is applied in a correlation function Monte Carlo calculation to compute ground…
Quantum Monte Carlo Methods in Statistical Mechanics
Vilen Melik-Alaverdian, M. P. Nightingale
This paper deals with the optimization of trial states for the computation of dominant eigenvalues of operators and very large matrices. In addition to preliminary results for the…
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…
Skyrmion Physics Beyond the Lowest Landau Level Approximation
V. Melik-Alaverdian, N. E. Bonesteel, G. Ortiz
The effects of Landau level mixing and finite thickness of the two-dimensional electron gas on the relative stability of skyrmion and single spin-flip excitations at Landau level f…
Monte Carlo Comparison of Quasielectron Wave Functions
V. Melik-Alaverdian, N. E. Bonesteel
Variational Monte Carlo calculations of the quasielectron and quasihole excitation energies in the fractional quantum Hall effect have been carried out at filling fractions …
