    General:  Theory of Semiconductors and Semiconductor Microstructures:


 

    Electronic Structure (wherever needed for a dynamical description of a system):

            Disorder in semiconductor alloys

            amorphous semiconductors and heterostructure
 
 
 

    Charge Transport:

            bridge macroscopic (classical) world to microscopic (quantum-mechanical) world

            contact problem,  open quantum systems, and dissipation
 
 

    (Quantum-)Optical Properties and Coherent Phenomena in Semiconductors:
 

            (a)  Coherent multiple-pulse excitation of semiconductor heterostructures:  gain w/o inversion, slowing of light,
            coherent control (of photo-absorption, final-state population, optical gain, phonon emission)

            (b) Structural (Fano) resonances and coherent control

            (c) Theory of optical excitations (e.g. four-wave mixing, excitonic effects, etc.)

            (d) Adiabatic manipulation of electronic transitions

            (e) Coupled electron-phonon dynamics

            (f)  Optimal Control of Quantum Processes

            (f) Spin systems
