Nonlinear dynamics in far-infrared driven quantum-well intersubband transitions
We study the effect of many-body interactions on the collective response of confined electrons in doped quantum-well (QW) heterostructures to intense far-infrared radiation. Absorption line shapes are computed both by numerically integrating the equations of motion and by using the appropriately tim...
