Coherent control of ultracold photoassociation.
1. INTRODUCTION Photoassociation, forming molecules from ultracold atoms using laser light, is a prime example of coherent control: The process is complex and poses many challenges, yet typically the molecular structure is simple enough to identify pathways for control. Laser cooling schemes that work for atoms 1−5 tend to fail for molecules, mainly due to the presence of many near-resonance li...
متن کاملCoherent transfer of photoassociated molecules into the rovibrational ground state.
We report on the direct conversion of laser-cooled 41K and 87Rb atoms into ultracold 41K87Rb molecules in the rovibrational ground state via photoassociation followed by stimulated Raman adiabatic passage. High-resolution spectroscopy based on the coherent transfer revealed the hyperfine structure of weakly bound molecules in an unexplored region. Our results show that a rovibrationally pure sa...
متن کاملIntroduction to ultracold molecules: new frontiers in quantum and chemical physics.
Chemical Physics M cooled to ultralow temperatures provide fundamental new insights to molecular interaction and reaction dynamics in the quantum regime. In recent years, researchers from various scientific disciplines such as atomic, optical, and condensed matter physics, physical chemistry, and quantum science have joined force to explore many emergent and exciting research topics that are en...
متن کاملDark state experiments with ultracold, deeply-bound triplet molecules.
We examine dark quantum superposition states of weakly bound Rb2 Feshbach molecules and tightly bound triplet Rb2 molecules in the rovibrational ground state, created by subjecting a pure sample of Feshbach molecules in an optical lattice to a bichromatic Raman laser field. We analyze, both experimentally and theoretically, the creation and dynamics of these dark states. Coherent wavepacket osc...
متن کاملPerspectives for coherent optical formation of strontium molecules in their electronic ground state
Optical Feshbach resonances Phys. Rev. Lett. 94, 193001 2005 and pump-dump photoassociation with short laser pulses Phys. Rev. A 73, 033408 2006 have been proposed as means to coherently form stable ultracold-alkali-metal dimer molecules. In an optical Feshbach resonance, the intensity and possibly frequency of a cw laser are ramped up linearly followed by a sudden switch-off of the laser. This...
