Research
My research effort primarily involves using and developing quantum Monte
Carlo methods to solve the many-body
Schrödinger equation. I am currently working on the properties of
clusters of atoms and molecules, the electronic structure of materials,
and the properties of neutron matter and nuclei.
When I last updated these, two recent publications which gave an idea of
the kind of calculations I do, were:
S. Fantoni, A. Sarsa, and K.E. Schmidt, Spin Susceptibility of Neutron
Matter at Zero Temperature," Phys. Rev. Lett. 87, 181101 (2001).
J.W. Moskowitz, Z. Bacic, A. Sarsa, and K.E. Schmidt,
"Relative stabilities of the two isomers of the methanol-water dimer:
The effects of internal rotations of the hydroxyl and methyl groups of
methanol," J. Chem. Phys. 114 10294 (2001).
For Fun
An applet to solve the 1-dimensional time independent Schrödinger Equation.
.
An applet to show the classical motion of a linear diatomic chain.
An applet to solve the transmission line equations.
An applet to model Yagi antennas.
An applet to do some conformal mappings;
note this requires a browser
with the Java plugin installed.
An applet to show the Kronig-Penney model of energy bands;
note this requires a browser

An applet to calculate electromagnetic scattering from a thin
straight wire;
note this requires a browser
with the Java plugin installed.
An applet to calculate the field lines of sets of charges in two or
three dimensions;
note this requires a browser
with the Java plugin installed.
An applet to solve the two-dimensional Laplace's equation for a circle in
a square;
note it requires a browser
with the Java plugin installed.
An applet to solve the 1-dimensional time independent Schrödinger Equation.
This is functionally identical to the first applet above, but looks nicer.
Note it requires a browser
with the Java plugin installed.
