Path Integral quantum Monte Carlo calculations for semiconductor nanostructures
Ian Galbraith
Department of Physics, Heriot-Watt University
In this lecture I will introduce the techniques of Path Integral Quantum Monte Carlo with particular application to the optical properties of semiconductor nanostructures such as dots and rings. Such calculations treat coulomb correlations and finite temperature effects on an equal footing avoiding any truncation at a particular order of interaction. As specific examples I will discuss exciton switching in quantum rings, diamagnetic susceptibility in quantum dots and rings as well as biexciton binding energies in core-shell colloidal quantum nanostructures.
