In 1997, a seminal paper of the time-resolved SHG study on a GaAs surface appeared [23], It was shown that the time-resolved SHG probes not only electronic dynamics but also lattice (phonon) dynamics. The detection scheme is as follows The pump pulse impulsively excites the longitudinal optical (LO) phonon in the GaAs...

One of the most exciting prospects in the study of phonon dynamics is the use of nonlinear optical phenomena to generate monochromatic, coherent phonon distributions and to detect their subsequent evolution. 

Although, SrTiOs is per se not ferroelectric even at low temperatures, it is very close to the ferroelectric threshold so that an isotopic replacement of oxygen ( 0 — 0) or partial cation substitution reduces quantum fluctuations and makes the material ferroelectric (Itoh et al., 1999 Choudhury et al., 2008). Hence the phonon dynamics as a function of temperature wiU be discussed using SrTi03 as a model substance.

In Sects. 3.2, 3.3 and 3.4, we have shown the way the information about an electron-phonon interaction and phonon dynamics can be got firom the homogeneous optical bands. However, these bands are hidden under strong inhomogeneous broadening existing in polymers and passes. Methods of selective spectroscopy enable one to remove inhomogeneous broadening. We discussed these methods briefly in Sect. 2.2. In this part, we consider methods of selective spectroscopy in more detail. 

We shall return to a dynamical treatment of phonon dynamics when dealing with atom/molecule surface scattering. 

FSSH prescribes a probability for hopping between electronic states. The probability is explicitly time dependent and is correlated with the nuclear evolution. The probability of hopping between states k and m within the time interval At depends explicitly on phonon dynamics and equals ...
