Reis Impulsive optical excitation can generate both coherent and squeezed phonons through first- and second-order Raman-like processes. The expectation value of the phonon displacement 〈 u q 〉 oscillates at the phonon mode frequency for the coherent state but remains zero for a pure squeezed state. In contr… [Phys. Rev.
