Abstract:
We study non-equilibrium association of Li2 Feshbach molecules over a range of temperatures T ≫ TF to T ≪ TF. We observe an enhancement of the atom–molecule coupling efficiency as the fermionic atoms reach degeneracy demonstrating the importance of manybody coherence not captured by the conventional LZ model [1]. We develop and detail a theoretical model that can explain the temperature dependence of the atom–molecule coupling and use it to predict a shortcut to adiabaticity in molecular association efficiency. I will also report on our recent results of a microscopic atom-photon interface [2], our 3D-printed elements for quantum technologies including 3D-printed UHV chambers and miniature 3D-printed vapour cells.
