Revision as of 21:09, 28 January 2010

We work on microcavity physics: the quantum coupling of light and matter in a cavity of micrometric size (realized with alternating layers of semiconductors).

The cavity can sandwich an entire plane, in which case the physics is in 2D, or it can circle around a single, atom-like object, typically a quantum dot, in which case it is 0D. (We focus on these two cases but 1D and 3D are also possible).

The 2D case is interesting for macroscopic degeneracy, with a lot of particles acting as one, with outreaches such as Bose-Einstein condensation, superfluidity, superconductivity, etc.

The 0D case is interesting for microscopic isolation, with a few quanta of excitations ruling the dynamics of the system, with outreaches such as entanglement, quantum information processing, etc.

Below is a picture of a spectral shape for a quantum dot in a microcavity in the nonlinear regime, with, superimposed, the so-called Jaynes-Cummings ladder, an insight into full-field quantization, where also the optical field is quantized, an extreme you don't usually require for most theoretical descriptions. This is this regime which interests us particularly.
