During the past decade the interaction of light with multiatom ensembles has attracted much
attention as a basic building block for quantum information processing and quantum state …

An overview of the physics of spinor and dipolar Bose–Einstein condensates (BECs) is
given. Mean-field ground states, Bogoliubov spectra, and many-body ground and excited …

Modern optical techniques allow one to accurately control light using atoms and to
manipulate atoms using light. In this Colloquium the author reviews several ideas indicating …

This paper reviews quantum spin squeezing, which characterizes the sensitivity of a state
with respect to SU (2) rotations, and is significant for both entanglement detection and high …

The purpose of this article is to review spontaneous emission from several different
viewpoints, although a large part of it will be devoted to the quantum statistical theories of …

Many-body entanglement is often created through the system evolution, aided by nonlinear
interactions between the constituting particles. These very dynamics, however, can also lead …

Interferometers with atomic ensembles are an integral part of modern precision metrology.
However, these interferometers are fundamentally restricted by the shot noise limit, which …

The standard quantum limit of measurement uncertainty can be surpassed using squeezed
states, which minimize the uncertainty product in Heisenberg's relation by reducing the …
