Abstract
Coherent control and light-heavy-hole beats observed in transient optical e xperiments in GaAs quantum wells are discussed in terms of a free-boson mod el. The properties of the exactly calculated wavefunction of the photoexcit ed system lead to a reinterpretation of the beats as due to classical elect romagnetic interference, in contrast to the widely used quantum description based on few-level representations.
