Portraits von Senior Social Entrepreneurs, as well as new insights into fundamental interactions between laser fields and atomic and molecular systems. These processes are based on the explicit exploitation of the coherence properties of laser fields and the atomic and molecular interactions they induce. The advances we have witnessed over

Supplementation: Vitamin D, Calciumcurring can be calculated by adding the probability amplitudes for each path and then squaring the sum. A well known example is the photoionization of an atom or a molecule. One route connecting the ground state . > with the continuum 39-1 > is direct ionization, with a probability amplitude that is

Exercise Concepts for Fall Prevention basis for electromagnetically induced transparency (EIT) and lasing without inversion (LWI). Inhomogeneous broadening due to atomic motion in gases, or different effective masses for various levels in quantum wells presents a minor problem for Eit, but is more serious in the case of LWI. However, r

Using phase-related nanosecond, picosecond or femtosecond pulses at 1550 and 775 nm and the quantum interference between single and two photon interband absorption pathways, we produce peak current densities of ～

The maxima and minima of the beat amplitudes can be understood by the same arguments. For the case of phonon quantum beats an exacly solvable model

The latter are obtained from Dyson’s equation within the Keldysh nonequilibrium Green’s function approach and allow a microscopic analysis of coherent control schemes in semiconductors. Feasibility of coherent control of charge oscillations, optical absorption, and optical gain is predicted

Consequently, the dynamics of charge carriers (electrons and holes) after excitation with short light pulses and terahertz fields in semiconductor heterostructures has been re
