Time-resolved, pulsed terahertz spectroscopy has developed into a powerful tool to study
charge carrier dynamics in semiconductors and semiconductor structures over the past …

The recent development of techniques to produce optical semiconductor cavities of very
high quality has prepared the stage for observing cavity quantum-electrodynamic effects in …

The optically excited system of electronic excitations in semiconductor nanostructures is
analyzed theoretically. A many-body theory based on an equation-of-motion approach for …

Many-body systems in nature exhibit complexity and self-organization arising from
seemingly simple laws. For example, the long-range Coulomb interaction between electrical …

Excitons are quasi-particles that form when Coulomb-interacting electrons and holes in
semiconductors are bound into pair states. They have many features analogous to those of …

The integrated absorption of an excitonic resonance is a measure of a semiconductor's
coupling to an optical field. The concept of an exciton–polariton expresses the non …

We report a comprehensive experimental study and detailed model analysis of the terahertz
dielectric response and density kinetics of excitons and unbound electron-hole pairs in …

An experiment-theory comparison is presented to demonstrate terahertz-induced extreme-
nonlinear transients in a GaAs/AlGaAs quantum-well system. The terahertz-pump and …

Time-resolved photoluminescence spectra after nonresonant excitation show a distinct 1 s
resonance, independent of the existence of bound excitons. A microscopic analysis …

In this chapter, we postulate an integral concept of information processing in the universe,
on the basis of a new biophysical principle, coined the generalized music (GM)-scale of EMF …
