Theoretical Condensed Matter Physics
Ph.D., Texas, Austin, 1966 Calculation of material properties using the Local Density Approximation. New algorithms for iterative convergence of quantum-mechanical computations, many-body extensions to the Local Density Approximation.
Currently there are projects involved in developing methods to allow hundreds of interacting atoms to be simulated dynamically. Some of these projects address the creation of new algorithms to enhance either computability or accuracy. Methods range from variational Monte Carlo techniques to Local Density Approximations. An underlying theme is the use of iterative solution methods so that very large problems may be attacked. We are also developing iterative solutions to the problem of exact response functions.
