Coherent Three-Photon Excitation of the Strontium Clock Transition
Junyu He, Benjamin Pasquiou, Rodrigo Gonzalez Escudero +3
We demonstrate coherent three-photon excitation of the strontium clock transition with a contrast of 51(12)% using a Bose-Einstein condensate. We follow it up with a demonstration…
Continuous Bose-Einstein condensation
Chun-Chia Chen, Rodrigo González Escudero, Jiří Minář +3
Bose-Einstein condensates (BECs) are macroscopic coherent matter waves that have revolutionized quantum science and atomic physics. They are essential to quantum simulation and sen…
Observation of Bose-enhanced photoassociation products
Alessio Ciamei, Alex Bayerle, Benjamin Pasquiou +1
We produce molecules using Bose-enhanced Raman photoassociation. We apply the stimulated Raman adiabatic passage (STIRAP) technique on a Bose-Einstein conden…
Efficient production of long-lived ultracold Sr molecules
Alessio Ciamei, Alex Bayerle, Chun-Chia Chen +2
We associate Sr atom pairs on sites of a Mott insulator optically and coherently into weakly-bound ground-state molecules, achieving an efficiency above 80\%. This efficiency is 2.…
Quantum degenerate mixtures of strontium and rubidium atoms
Benjamin Pasquiou, Alex Bayerle, Slava Tzanova +5
We report on the realization of quantum degenerate gas mixtures of the alkaline-earth element strontium with the alkali element rubidium. A key ingredient of our scheme is sympathe…
Laser cooling to quantum degeneracy
Simon Stellmer, Benjamin Pasquiou, Rudolf Grimm +1
We report on Bose-Einstein condensation (BEC) in a gas of strontium atoms, using laser cooling as the only cooling mechanism. The condensate is formed within a sample that is conti…
