  1. Researchers have created a one-dimensional “quantum wire” made from a #gas of #ultracold atoms, where #mass and #energy flow without friction or loss.

  2. Researchers from Hanns-Christoph Nägerl's group have produced the world’s first #ultracold #KCs #molecules in their absolute ground state. Starting by mixing clouds of potassium and caesium atoms cooled almost to absolute zero temperature

  3. "Here..we report, to our knowledge, the first simultaneous production of a dual-species BEC in space (formed from 87Rb & 41K), observation of interspecies interactions, as well as the production of 39K #ultracold gases. Operating a single #laser at a ‘magic wavelength’ at which Rabi rates of simultaneously applied Bragg pulses are equal, we have further achieved the first spaceborne demonstration of simultaneous atom #interferometry with 2 atomic species (87_Rb & 41_K)"

  4. New review paper on the recent striking advances in the manipulation and #quantum science of #ultracold #molecules. Great collaboration with Giacomo Valtolina (Fritz-Haber-Institut, Berlin), Dajun Wang (CUHK, Hong Kong) and Jun Ye (JILA, Boulder).

    Hope this is useful to those new (and maybe not so new) to this exciting field!
