Journal ArticleDOI
Quantum-State Controlled Chemical Reactions of Ultracold Potassium-Rubidium Molecules
Silke Ospelkaus,Kang-Kuen Ni,Dajun Wang,M. H. G. de Miranda,Brian Neyenhuis,Goulven Quéméner,Paul S. Julienne,John L. Bohn,Deborah Jin,Jun Ye +9 more
TL;DR: Experimental evidence for exothermic atom-exchange chemical reactions is reported, starting with an optically trapped near–quantum-degenerate gas of polar 40K87Rb molecules prepared in their absolute ground state.
Journal ArticleDOI
Creation of ultracold molecules from a Fermi gas of atoms
TL;DR: The creation and quantitative characterization of ultracold 40K2 molecules is reported, which can be converted back to atoms by reversing the scan, and the small binding energy of the molecules is controlled by detuning the magnetic field away from the Feshbach resonance, and can be varied over a wide range.
Journal ArticleDOI
Dipolar collisions of polar molecules in the quantum regime
Kang-Kuen Ni,Silke Ospelkaus,Silke Ospelkaus,Dajun Wang,Goulven Quéméner,Brian Neyenhuis,M. H. G. de Miranda,John L. Bohn,Jun Ye,Deborah Jin +9 more
TL;DR: It is shown how the long-range dipolar interaction can be used for electric-field control of chemical reaction rates in an ultracold gas of polar molecules, and how this dependence can be understood in a relatively simple model based on quantum threshold laws for the scattering of fermionic polar molecules.
Journal ArticleDOI
Hartree-Fock Theory for Double Condensates
TL;DR: Myatt et al. as mentioned in this paper presented a theoretical treatment that accounts in detail for a recent observation of overlapping Bose-Einstein condensates of two different hyperfine states, which explains the manner in which one condensate partially wraps around the other.
Journal ArticleDOI
Controlling the quantum stereodynamics of ultracold bimolecular reactions
M. H. G. de Miranda,A. Chotia,Brian Neyenhuis,Dajun Wang,Dajun Wang,Goulven Quéméner,Silke Ospelkaus,John L. Bohn,Jun Ye,Deborah Jin +9 more
TL;DR: In this paper, an optical lattice trap is used to confine the fermionic polar molecules in a quasi-two-dimensional, pancake-like geometry, with the dipoles oriented along the tight confinement direction.
