Quantum Distribution FunctionsThe quantum kinetic equation is in the slowly-varying center-of-mass coordinate approximation expressed in terms of the Wigner function. The collision integral is simplified by means of the generalized Kadanoff—Baym ansatz formulated in a gauge invariant way which respects causality.

Transport in Mesoscopic Semiconductor StructuresStationary transport properties of tunneling structures such as doublebarrier semiconductor heterostructures, superlattices, metallic nanowires, and Coulomb blockade structures are treated as examples for quantum transport through mesoscopic systems

Optical Free-Carrier Interband Kinetics in SemiconductorsThe kinetics of the interband transitions in optically excited semiconductors is discussed and a brief historic review of this field is given. As an introductory example the free-carrier kinetics is formulated in terms of nonequilibrium Green functions, resulting in the semiconductor optical Bloch equations.

Optical Absorption in Intense THz Fieldsssed in terms of nonequilibrium Green functions. A number of special cases are calculated explicitly. The approach is generalized to include excitonic effects. Finally the theoretical predictions are compared to measured spectra.

ental stress on organisms is presented. Two main inputs of heavy metals for terrestrial ecosystems have been considered: airborne and soil-borne..Airborne metals can be monitored due to physical adsorption on plant surfaces or due to chemical exchange processes in cell walls. Active biomonitoring wi
