Personnel

Project Leader(s):
Cai-Zhuang Wang

Principal Investigators:
Vladimir Antropov, Viatcheslav Dobrovitski, Kai-Ming Ho, Costas Soukoulis, Cai-Zhuang Wang,

Overview

The scope of this project is to generate new theories, models, and algorithms that will be beneficial to the research program at Ames Laboratory and to the mission of DOE. The need to make quantitative theoretical predictions and to obtain detailed agreement between theory and experiment are crucial for the design, characterization, and control of complex materials. This project focuses on the development of theoretical tools which will be used to study a broad range of problems in physics, materials science, and chemical as well as biological systems.

Research subtasks in this project will include:

  • Methods for accurate calculation of strongly correlated electron systems.
  • Methods for large scale atomistic simulation of complex structures & materials.
  • Methods for studying the dynamics of non-equilibrium or nonlinear systems.
