Rabi oscillations of two-dimensional electrons under ultrafast intersubband excitation

We investigate coherent nonlinear dynamics of two-dimensional electrons under ultrafast intersubband excitation by mid-IR pulses. We include the effects of relaxation and dephasing, both homogeneous and inhomogeneous, as well as detuning within a non-Markovian equation to obtain temporal population redistributions. We show how, using a cross-correlation method, the effects of Rabi oscillations may be detected in this system, and briefly discuss detection based on terahertz emission of radiation from nonsymmetric quantum wells.
