Kastler–Brossel Laboratory

The Kastler–Brossel Laboratory, located in Paris, France, is a research laboratory specializing in fundamental physics of quantum systems. Founded in 1951 by Alfred Kastler and Jean Brossel, it is a joint research unit operated by the French National Centre for Scientific Research (CNRS), the École normale supérieure, the Sorbonne University and the Collège de France.

Brief history

The laboratory was founded in 1951 by Alfred Kastler (Nobel Prize in Physics in 1966) and Jean Brossel on the theme of the interaction between light and matter. The initial name of laboratory was the « Laboratoire de spectroscopie Hertzienne de l'ENS ». It is located in the Department of Physics of École normale supérieure.

In 1967, a second site opened on the Jussieu campus.

In 1994, the laboratory changed its name to « Laboratoire Kastler Brossel » in honor of its two founders.

Now, the Kastler Brossel Laboratory (LKB) is one of the main actor in the field of fundamental physics of quantum systems.

Research activity

Many new themes have appeared recently in the field of fundamental physics of quantum systems, like quantum entanglement or Bose–Einstein condensation in gases, which leads to a constant renewal of the research carried out in the laboratory. Presently its activity takes several forms: cold atoms (bosonic and fermionics systems), atom lasers, quantum fluids, atoms in solid helium; quantum optics, cavity quantum electrodynamics; quantum information and quantum theory of measurement; quantum chaos; high-precision measurements. These themes lead not only to a better understanding of fundamental phenomena, but also to important applications, like more precise atomic clocks, improvement of detectors based on atomic interferometry or new methods for biomedical imaging.

People
gollark: Yes, because they have been (are? not sure) lagging behind with modern technological things, and so need(ed?) to use English-programmed English-documented things.
gollark: Which means piles of technical docs are in English, *programs* are in English, people working on technological things are using English a lot...It probably helps a bit that English is easy to type and ASCII text can be handled by basically any system around.
gollark: I don't think it was decided on for any sort of sane reason. English-speaking countries just dominated in technology.
gollark: It's probably quite a significant factor in pushing English adoption.
gollark: Indeed; most programming stuff is still mostly English.
