Coherent, collective decay due to spontaneous emission. Observed in atomic systems (HF gas etc.), here prediction for semiconductors in strong magnetic field or quantum dot array  Quantum optical effects in electronic systems                              (see publications).
Change of impurity scattering and DC conductivities in presence of additional, time-dependent `pump fields' Time-dependent phenomena, transport in AC driven systems     (see publications).
Conductance change due to electron-phonon and electron-electron interaction. In wires with N channels, 1/N temperature exponent (experimentally confirmed by Tarucha et al.) Interactions in quantum wires (multichannel, Luttinger liquid)       (see publications).
Multifractal exponents eta for metal-insulator transitions appear in experimentally relevant inelastic scattering rates Electronic transport in mesoscopic systems, interaction effects    (see publications).
