Hydrodynamic approach on the kinetic theory of electron liquids and dynamic density functional theory

project description

Unlike the established static density functional theory the time-dependent version of this theory is inherently non-local. According to this the construction of the dynamic exchange-correlation-functional is a much more complex task. It is possible to simplify matters by considering the long wave limit of quasi-homogeneous systems. In this case the TDDFT for interacting many-body-Fermi-systems reduces to a combination of elasticity theory and hydrodynamics. This method's straight application is the calculation of collective excitations in an electron liquid, which are embedded in different quantum structures (quantum wells, quantum wires and quantum dots) or enclosed at metallic surfaces.
