We report on the high resolution studies of the temperature (T) dependence of the q = 0 phonon spectrum in the quasi-one-dimensional charge density wave (CDW) compound Ko.3Mo03 utilizing timeresolved optical spectroscopy, Numerous modes that appear below Tc show pronounced T dependences of their amplitudes, frequencies, and dampings. Utilizing the time-dependent Ginzburg-Landau theory we show that these modes result from linear coupling of the electronic part of the order parameter to the 2kF… CONTINUE READING
