Ultrafast Enhancement of Ferromagnetism via Photoexcited Holes in GaMnAs
J. Wang, I. Cotoros, K. M. Dani +3
We report on the observation of ultrafast photo-enhanced ferromagnetism in GaMnAs. It is manifested as a transient magnetization increase on a 100-ps time scale, after an initial s…

Ultrafast Nonlinear Optical Response of Strongly Correlated Systems: Dynamics in the Quantum Hall Effect Regime
A. T. Karathanos, I. E. Perakis, N. A. Fromer +1
We present a theoretical formulation of the coherent ultrafast nonlinear optical response of a strongly correlated system and discuss an example where the Coulomb correlations domi…
