Vibronic coupling limits the use of high-lying electronic states in complex molecules for laser cooling
Haowen Zhou, Pawel Wojcik, Guo-Zhu Zhu +7
Laser cooling of large, complex molecules is a long-standing goal, instrumental for enabling new quantum technology and precision measurements. A primary consideration for the feas…
Laser spectroscopy of aromatic molecules with optical cycling centers: strontium (I) phenoxides
Guanming Lao, Guo-Zhu Zhu, Claire E. Dickerson +5
We report the production and spectroscopic characterization of strontium (I) phenoxide (, or SrOPh) and variants featuring electron-withdrawing groups…
Pathway Towards Optical Cycling and Laser Cooling of Functionalized Arenes
Debayan Mitra, Zack D. Lasner, Guo-Zhu Zhu +8
Rapid and repeated photon cycling has enabled precision metrology and the development of quantum information systems using a variety of atoms and simple molecules. Extending optica…
Functionalizing Aromatic Compounds with Optical Cycling Centers
Guo-Zhu Zhu, Debayan Mitra, Benjamin L. Augenbraun +9
Molecular design principles provide guidelines for augmenting a molecule with a smaller group of atoms to realize a desired property or function. We demonstrate that these concepts…
Franck-Condon tuning of optical cycling centers by organic functionalization
Claire E. Dickerson, Han Guo, Ashley J. Shin +4
Laser induced electronic excitations that spontaneously emit photons and decay directly to the initial ground state ("optical cycling transitions") are used in quantum information…
