Change of electronic properties due to ultrashort laser pulses

Kurzfassung

We begin with a short discussion of existing approaches to the description of nonequilibrium processes and the possibil-ity of how to overcome the problem of the definition of temperature in this case. Next, we explain why the equations of fluxes and conductivities as derived in standard solid state theory have to be reconsidered. Starting from the Boltzmann equation then we derive expressions for the thermal and electrical conductivity with new qualitative and quantitative properties. These results are supported by comparison with experiments.
