General introduction
Our activity on cryogenic atom traps has started in 2001. Our long term goal is to realize a new kind of experiments where an individual atoms in a superposition of Rydberg states could be trapped and interact together or with a surface for very long times in the second range.
This requires the development of new experimental techniques, which should in themselves have a scientific interest. We are particularly working on superconducting atom chips, which would allow us to study the behavior of ultracold atoms in the vicinity of a radically new environment, where the quantum is already present.
We are also developing a detector for the Rydberg states which could be integrated on the chip. Rydberg atoms can be easily ionised and we would like to detect the outgoing electron. We are trying to extend the present ideas on superconducting photon detectors to the case of single electron.
You can visit us in room R14, in the physics department of ENS. Our lab phone number is +33 1 44 32 25 08.
