           "A Raman study of competing ordering phenomena in cuprates"

        Abstract: Raman (inelastic light) scattering is a relatively new 
        and alternative method to study electronic properties such as the 
        conductivity. In addition to infrared spectroscopy some resolution 
        in k-space can be achieved which allows, for instance, to measure 
        the momentum dependence of the energy gap of a superconductor. In 
        my presentation I will discuss results of inelastic light 
        scattering experiments in copper oxygen compounds in the normal 
        and in the superconducting state. The strong doping dependence of 
        the transport properties in the normal state, the tendency to 
        charge ordering at low doping and the renormalization at $T_c$ of 
        the response at high energies will be addressed.
