Theory of nonlinear optical spectroscopy of electron spin coherence in quantum dots (2006)
Liu, Ren-Bao, Economou, S. E., Sham, L. J., Steel, D. G.
We study in theory the generation and detection of electron spin coherence in nonlinear optical spectroscopy of semiconductor quantum dots doped with single electrons. In third-order differential...
Emary, C., Xu, Xiaodong, Steel, D. G., Saikin, S., Sham, L. J.
We consider the initialization of the spin-state of a single electron trapped in a self-assembled quantum dot via optical pumping of a trion level. We show that with a magnetic field applied...
Unravelling ecological analysis (2006)
D. G. Steel, M. Tranmer, D. Holt
Ecological analysis involves analysing aggregate data for groups of individuals to make inferences about relationships at the individual level. Often the results of such analyses give badly biased...
