Laboratoire Kastler Brossel (LKB/ENS-PSL, SU, CdF)

About LKB:

The Kastler Brossel Laboratory (LKB) is a joint research unit of the Ecole Normale Supérieure, Sorbonne University, Collège de France and CNRS It is one of the main leaders worldwide in the domain of fundamental physics of quantum systems, covering numerous subjects from fundamental tests of quantum theory to applications, with an internationally recognized expertise throughout its 65 years history, including three Nobel Prize winners.

The traditional activities of the laboratory is in atomic physics and optics, with a particular emphasis in fundamental issues of light-matter interaction, quantum states of light and precision spectroscopy. One of the important developments in recent decades concerns cooling and trapping of neutral atoms, which have opened up a rich field of study on quantum gases and liquids, at the boundary between atomic and condensed matter physics. Another strength of the laboratory is the study of the interaction between photons and atoms with fundamental contributions in the field of cavity quantum electrodynamics, quantum optics and quantum information, and optomechanics. While these concepts continue to play a central role at LKB, the laboratory has also diversified its research themes towards nanophotonics, Casimir effect, imaging in biological and complex media, trapped ions, metrology and the tests of fundamental interactions. LKB participates in several large-scale programs and collaborations at the national and international levels such as GBAR, Virgo, several space missions and French programs of excellence (Equipex).

Research and organization of the laboratory

The laboratory is composed of a majority of young researchers, with 56 researchers, professors and assistant professors, about 70 PhD students and 30 post-doctoral students. The laboratory is composed of 12 research teams distributed into 5 axes:

– Quantum gases

– Quantum optics and quantum information

– Atoms and light in dense or complex media

– Tests of fundamental interaction and metrology

– Frontiers and applications
