Observation of Microwave Shielding of Ultracold Molecules
Loic Anderegg,Loic Anderegg,Sean Burchesky,Sean Burchesky,Yicheng Bao,Yicheng Bao,Scarlett S. Yu,Scarlett S. Yu,Tijs Karman,Tijs Karman,Eunmi Chae,Kang-Kuen Ni,Kang-Kuen Ni,Wolfgang Ketterle,John M. Doyle,John M. Doyle +15 more
TL;DR: In this paper, the authors used microwave radiation to directly engineer and tune the interaction potentials between ultracold calcium monofluoride (CaF) molecules by merging two optical tweezers, each containing a single molecule, to probe collisions in three dimensions.
Journal ArticleDOI
Elliptical polarization for molecular Stark shift compensation in deep optical traps
TL;DR: In this paper, it was shown that the light shift for a sublevel of excited rotational states approaching that of the ground state at high optical intensity can be nulled by choice of elliptical polarization.
Journal Article
Suppression of extraneous thermal noise in cavity optomechanics
TL;DR: An active noise suppression scheme and its experimental implementation is presented and its application in a cavity-optomechanical system is described.
Journal ArticleDOI
Ultracold polar molecules near quantum degeneracy
Silke Ospelkaus,Kang-Kuen Ni,M. H. G. de Miranda,Brian Neyenhuis,Dajun Wang,Svetlana Kotochigova,Paul S. Julienne,Deborah Jin,Jun Ye +8 more
TL;DR: The creation and characterization of a near quantum-degenerate gas of polar 40K-87Rb molecules in their absolute rovibrational ground state and the measurement of the molecular polarizability in an optical dipole trap where the trap lifetime gives clues to interesting decay mechanisms.
Journal ArticleDOI
A low-temperature external cavity diode laser for broad wavelength tuning
William G. Tobias,Jason S. Rosenberg,Jason S. Rosenberg,Nicholas R. Hutzler,Nicholas R. Hutzler,Kang-Kuen Ni,Kang-Kuen Ni +6 more
TL;DR: The design and characterization of a low-temperature external cavity diode laser (ECDL) system for broad wavelength tuning addresses the scarcity of commercial red laser diodes below 633 nm, which is a wavelength range relevant to the spectroscopy of many molecules and ions.
