Kinetic Monte Carlo Simulations of Crystal Growth in Ferroelectric Alloys
Malliga Suewattana, Henry Krakauer, Shiwei Zhang
The growth rates and chemical ordering of ferroelectric alloys are studied with kinetic Monte Carlo (KMC) simulations using an electrostatic model with long-range Coulomb interacti…
Accurate, efficient and simple forces with Quantum Monte Carlo methods
Simone Chiesa, David Ceperley, Shiwei Zhang
Computation of ionic forces using quantum Monte Carlo methods has long been a challenge. We introduce a simple procedure, based on known properties of physical electronic densities…
Quantum Monte Carlo method for the ground state of many-boson systems
Wirawan Purwanto, Shiwei Zhang
We formulate a quantum Monte Carlo (QMC) method for calculating the ground state of many-boson systems. The method is based on a field-theoretical approach, and is closely related…
