Hyperfine-to-rotational energy transfer in ultracold atom-molecule collisions

Yi-Xiang Liu, Lingbang Zhu, Jeshurun Luke, Mark Babin et autres

Energy transfer between different mechanical degrees of freedom in atom-molecule collisions has been widely studied and largely understood. However, systems involving spins remain less explored, especially with a state-to-state precision. Here, we directly observed the energy transfer from atomic hyperfine to molecular …

Quantum interference in atom-exchange reactions

Yi-Xiang Liu, Lingbang Zhu, Jeshurun Luke, J. J. A. Houwman et autres

Chemical reactions, in which bonds break and form, are highly dynamic quantum processes. A fundamental question is whether coherence can be preserved in chemical reactions and then harnessed to generate entangled products. Here we investigated this question by studying the 2KRb → …

Quantum interference and entanglement in ultracold atom-exchange reactions

Yi-Xiang Liu, Lingbang Zhu, Jeshurun Luke, J. J. Arfor Houwman et autres

Coherent superpositions and entanglement are hallmarks of quantum mechanics, but they are fragile and can easily be perturbed by their environment. Selected isolated physical systems can maintain coherence and generate entanglement using well-controlled interactions. Chemical reactions, where bonds break and form, are …

High-Resolution Photoelectron Spectroscopy of Vibrationally Excited Vinoxide Anions

Jascha A. Lau, Martin DeWitt, Mark A. Boyer, Mark Babin et autres

High-resolution photoelectron spectra of vibrationally pre-excited vinoxide anions (CH 2 CHO – ) are reported using the recently developed IR-cryo-SEVI technique. This method is combined with a newly developed implementation of vibrational perturbation theory that can readily identify relevant anharmonic couplings among …

High-Resolution Photoelectron Spectroscopy of Vibrationally Excited Vinoxide Anions

Jascha A. Lau, Martin DeWitt, Mark A. Boyer, Mark Babin et autres

High-resolution photoelectron spectra of vibrationally pre-excited vinoxide anions (CH2CHO‒) are reported using the recently developed IR-cryo-SEVI technique. This method is combined with a newly developed implementation of vibrational perturbation theory that can readily identify relevant anharmonic couplings among nearly degenerate vibrational states. …

High Resolution Photoelectron Spectroscopy of the Acetyl Anion

Martin DeWitt, Mark Babin, Jascha A. Lau, Tonia Solomis et autres

High-resolution photoelectron spectra of cryogenically cooled acetyl anions (CH 3 CO – ) obtained using slow photoelectron velocity-map imaging are reported. The high resolution of the photoelectron spectrum yields a refined electron affinity of 0.4352 ± 0.0012 eV for the acetyl radical …
