SPECIAL AMO PHYSICS SEMINAR
"Quantum optics with semiconductor
Sandia National Labs
There is recent interest in strong light-matter interaction in semiconductors
and its uses in optoelectronics. Exploring these possibilities requires
extending the Jaynes-Cummings model to include many-body effects. The
reason is that the matter, even for a single quantum dot (QD), consists of
multiple interacting charged particles.
I will show why the customary cluster expansion has a difficult time doing the job because of slow convergence. Then, I will describe an alternate approach that allows numerical integration of coupled electron-photonphonon equations of motion to arbitrary accuracy. If time allows, I will describe an example of recent experimental progress, involving Rabi oscillations in Sandia’s electrically (incoherently) excited mid-IR emitters.
