The electric field shielding method developed by members of the THEOMOL team (G. Quéméner, L. Lassablière) has been observed experimentally for the first time in an ultracold gas of KRb molecules. This experiment was performed at JILA by the team of Jun Ye. It is shown that it is possible to reduce the loss rate coefficients by a factor of 30, as theoretically expected. This work demonstrates full control of a long-lived quantum gas system with tunable long-range interactions, paving the way for the study of collective many-body quantum physics.
