Effects Of Disorder

A theory for electronic Raman scattering in the cuprate superconductors is presented with a specific emphasis on the polarization dependence of the spectra which can infer the symmetry of the energy gap. Signatures of the effects of disorder on the low frequency and low temperature behavior of the Raman spectra for different symmetry channels provide detailed information about the magnitude and the phase of the energy gap. Properties of the theory for finite T will be discussed and compared to recent data concerning the doping dependence of the Raman spectra in cuprate superconductors, and remaining questions will be addressed.

Low Temperature Specific Heat

Raman scattering and low temperature specific heat (Cp) measurements have been performed to investigate the low frequency vibrational dynamics of hen egg white dry lysozyme. The occurrence of low energy extra excitations have been revealed both in the light scattering spectrum and in theCp/T3vs. T plot. A perfect agreement in the frequency and temperature position of the Boson Peak in this protein has been observed. At temperature below 3 K it has been found a contribution to the specific heat similar to that revealed in glassy systems. This, together with the other analogies discovered between thermal properties of amorphous and biological systems, suggests the possibility of making the most of the knowledge about the former in order to understand some glassy-like behaviours of proteins.
