To illustrate the nature of the large variance problem when using certain GTO basis set/pseudopotential combinations, we summarize in Table 2.1.1 the

ABSTRACT QUANTUM MONTE CARLO STUDIES OF FERMI SYSTEMS IN LATTICE EFFECTIVE FIELD THEORY By Rongzheng He With the rapid growth of the computational resources, quantum Monte Carlo

Ab initio theory for nuclei and nuclear matter Degrees of freedom: nucleons.  Quantum Monte Carlo (GFMC)

In this thesis, I present two new quantum Monte Carlo techniques, the Monte Carlo Power Method and Bose-Fermi Auxiliary-Field Quantum Monte Carlo, and apply previ- ously developed

Typically, the trial wave function optimization involves the optimization of the coefficients in the determinant expansion of the Slater part, basis functions in the Jastrow

Computing dynamic response functions from quantum correlation functions is a popular chal- lenge amongst quantum Monte Carlo methods, such as path-integral Monte Carlo (PIMC),

I generalized the implementation of the force methods using Reptation Monte Carlo, tested several methods consistently, and found none of them accurate enough on transition

The setup of the Reversible Jump Markov Chain Monte Carlo (RJMCMC) is ideally suited for comparing different dimensional parametric models for the data.. In the reversible

Of the top 5 questionable medical claim policy types in 2009, General Liability (36 percent) and Commercial Auto (22 percent) had the largest percentage increases and Homeowners

Variational and diffusional Monte Carlo calculations of excitations in solids are computationally demanding because excitation energies are ‘‘1/N’’ effects; that is, the

We have shown that the neon pair potential determined by DMC calculations gives a more accurate EOS than the pair potential determined by CCSD 共 T 兲 calculations, although the

In Chap- ter 5, we will use the developed chiral NN potentials in QMC calculations to study the neutron matter equation of state up to nuclear densities at different chiral orders
