摘要：

Coherent control and light-heavy-hole beats observed in transient optical experiments in GaAs quantum wells are discussed in terms of a free-boson model. The properties of the exactly calculated wavefunction of the photoexcited system lead to a reinterpretation of the beats as due to classical electromagnetic interference, in contrast to the widely used quantum description based on few-level representations.
