There are five main research axes in the laboratory:

  • ultra-cold atom physics,
  • atom-surface interactions,
  • ultra-high resolution spectroscopy,
  • organic photonics,
  • life-science applications of lasers.

The laboratory is operatively structured into eight groups (See here the research flow chart). Their research topics are often complementary. They are rapidly presented below through key-words. The groups’ webpages give a more detailed description of their respective projects.

 

Dipolar quantum gases

Ultracold chromium atoms. Ultracold strontium atoms. Degenerate quantum gases. Bose-Einstein condensate. Fermi sea. Dipolar interactions. Quantum magnetism. Highly correlated quantum states.

 

Bose-Einstein condensates

Rubidium Bose-Einstein condensates. Superfluidity in low-dimensional and annular quantum gases. Atom chip for sodium.

 

Interferometry and optics for atoms

Quantum coherence of atomic waves. Beams of metastable rare gas atoms. Atom optics at nanometric scale. Interactions of atoms with micro- and nano-structured surfaces. Stern-Gerlach atom interferometry.

 

Atomic spectroscopy at interfaces

Atomic spectroscopy close to a surface. Van der Walls and Casimir-Polder interactions. Effect of a non-zero temperature. Confinement of atoms within opals and ultra-thin vapor cells. Interaction between an atom and a Laguerre-Gauss beam. Nano-optics. Quasi-forbidden transitions. Chiral properties.

 

Metrology, molecules and fundamental tests

Ultra-high resolution molecular spectroscopy. Test of parity non-conservation. Optical frequency metrology. Frequency reference transfer. Theoretical methods in atomic interferometry. Optical determination of the Boltzmann constant. Stabilization of visible and IR lasers.
