Coherent Phonons: Experiment,ief history of experiments and phenomenological theories of coherent phonons. A typical example of the experimental technique and results of coherent phonons using a pump and probe protocol is explained. Several selected examples of coherent phonons in semiconductors and semimetals are presented. In

Coherent Phonons: Quantum Theory,l. Two electronic states coupled with displaced harmonic oscillators, which represent phonons, are used. The dipole interaction between an optical pulse and the system is assumed and treated as a perturbation interaction. Time evolution of the density operator is calculated using the second-order pe
