... 1976)9 had found application mostly as a tool of high-resolution spectroscopy, rather than as a new direction in nonlinear optics. Therefore, the concept of EIT has contributed a distinctive new thrust to work on atomic coherence and its applications—a thrust, which is of direct interest to optical ...

Chapter 7 Fluorescence Imaging of Quantum Gases

... Fluorescence detection yields a single-atom resolved image in a single experimental run. Therefore, it is possible to extract correlations between different lattice sites. Two-site parity parity correlation functions were studied across the superfluid Mott insulator transitions in 2D and 1D systems. ...

This is not quite true for the 3D case, because for each q there are actually three different modes, one longitudinal and two transverse, associated with the same value ...

Population inversion

In science, specifically statistical mechanics, a population inversion occurs while a system (such as a group of atoms or molecules) exists in a state with more members in an excited state than in lower energy states. It is called an ""inversion"" because in many familiar and commonly encountered physical systems, this is not possible. The concept is of fundamental importance in laser science because the production of a population inversion is a necessary step in the workings of a standard laser.
