Coherent preparation by laser light of quantum states of atoms and molecules can lead to
quantum interference in the amplitudes of optical transitions. In this way the optical …

The authors discuss the technique of stimulated Raman adiabatic passage (STIRAP), a
method of using partially overlap** pulses (from pump and Stokes lasers) to produce …

E lectromagnetically induced transparency is a technique for eliminating the effect of a
medium on a propagating beam of electromagnetic radiation. EIT may also be used, but …

In crystals, energy band extrema in momentum space can be identified by a valley index.
The internal quantum degree of freedom associated with valley pseudospin indices can act …

Publisher Summary This chapter describes the coherent population trap** in laser
spectroscopy. Coherent population trap** may be also described as the pum** of the …

We present here a quantum Carnot engine in which the atoms in the heat bath are given a
small bit of quantum coherence. The induced quantum coherence becomes vanishingly …

The subject of electromagnetically induced transparency (EIT) is reviewed in this paper.
Emphasis is placed on the experimental work reported in this field since 1990. Theoretical …

We analyze elementary properties of exciton and polariton lasers—devices that generate
coherent optical and matter waves using final-state stimulation of exciton-phonon scattering …

We develop a theory of electromagnetically induced transparency in a three-level, ladder-
type Doppler-broadened medium, paying special attention to the case where the coupling …

Written by two of the world's leading researchers in the field, this is a systematic introduction
to the fundamental principles of coherent control, and to the underlying physics and …
