The authors review the physics of ultrafast dynamics in semiconductors and their
heterostructures, including both the observed experimental phenomena and the theoretical …

Femtochemistry addresses fundamental processes of chemical reaction dynamics such as
bond formation and breaking, which occur typically on a femtosecond time scale (1 fs) 10-15 …

Current experimental and theoretical progress toward the goal of controlling quantum
dynamics is summarized. Two key developments have now revitalized the field. First …

Molecular vibrations have oscillation periods that reflect the molecular structure, and are
hence being used as a spectroscopic fingerprint for detection and identification. At present …

Abstract The Tannor-Rice pump-dump scheme for controlling the selectivity of product
formation in a chemical reaction is improved by development of a method for optimizing the …

Coherent quantum control,, has attracted interest as a means to influence the outcome of a
quantum-mechanical interaction. In principle, the quantum system can be steered towards a …

We present a novel approach to the control of selectivity of reaction products. The central
idea is that in a two‐photon or multiphoton process that is resonant with an excited …

Generating attosecond pulses has required a radically different approach from previous
ultrafast optical methods. The technology of attosecond measurement, however, is built on …

We report on the formation of translationally cold Cs 2 ground-state molecules through
photoassociation of laser-cooled cesium atoms in a magneto-optical trap. The cold …

The observation of coherent dynamics ensuing from the excitation of molecular systems by
femtosecond laser pulses is at the heart of femtochemistry. The time-dependent evolution of …
