分子精密光谱与物理精密测量(Precision Spectroscopy and Precision Measurement using Polar Molecules)

The fundamental particles may possess permanent electric dipole moments (EDMs) that may be able to explain the T-reversal violation or Charge-Parity violation, the asymmetry of anti-matter over matter and so forth. Different models beyond the Standard Model predict EDM values which are attainable nowadays by the aid of the laser technology,molecular beam development and other techniques. Here we plan to carry out a fully optical double-resonance quantum beat measurement of the electron’s Electric Dipole Moment(eEDM) using a heavy diatomic molecule PbF. The molecular beam of molecules created in a buffer gas cooling apparatus enters a region of spacewhere it is polarized and a specific mixture of quantum states is selected. The beam travels an appropriate distance, and then the quantum state is probed to determine the quantum phase accumulated between the state preparation and probe steps. Here we seek tomove towards a new upper limit on the eEDM using a beam of PbF molecules that travel 40 cm through a region of uniform electric field in an optical quantum beat experiment. We also plan to test the precision of our calculations of geometric phase by implementing a voltage-controlled geometric phase rotator. Finally, if time permits, we will evaluate Stark guides for their suitability in an eEDM measurement. By allowing state-selected molecules to be guided in a long two-dimensional trap, a guided eEDM measurement would achieve coherence times that are comparable to the ion trap, but with countrates comparable to a conventional molecular beam machine.

分子反应动力学(Molecular Reaction Dynamics: Chemistry in the Universe)

The overeaching goal of this project is to explore experimentally in an innovative ultra-high vacuum space simulation chamber the formation of key classes of complex organic molecules (COMs) – organic molecules containing atoms of carbon, hydrogen, oxygen, and nitrogen - upon interaction of ionizing radiation in the form of galactic cosmic rays (GCRs) and Lyman α photons with interstellar ice analog samples and to constrain the level of mole­cu­lar com­ple­xity of organic molecules that can ultimately be synthesized in the interstellar medium (ISM). These key classes are aldehydes(HCOR), ketones (RCOR'), carboxylic acids (RCOOH), esters (RCOOR'), amides (RCONH2), and isocyanates (RNCO). Those objectives are achieved by syste­ma­ti­cally replicating the condi­tions of ice-coated interstellar grains in a novel, next-generation ultra-high va­cu­um surface scat­tering ma­chi­ne thro­ugh the exposure of interstellar ice analog samples resembling ices in cold molecular clouds as well as in low- and high-mass star forming regions at astrophysically rele­va­nt tem­pe­ra­tures (10 K to 50 K) to ioni­zi­ng radiation in form of secondary electrons generated in the track of galactic cosmic rays and Lyman α photons (10.2 eV). This research follows a radically distinct approach and applies a transformative methodology by probing the synthesis of COMs on line and in situ via com­ple­men­tary de­tec­t­ion schemes in the condensed phase (Infrared, Raman, UVVIS) and upon sub­li­mation of COMs into the gas phase via the progressive techno­logy of tunable, fragment-free vacuum ultraviolet (VUV) photoionization.This unique space simulation chamber allows the extraction of transformative concepts on the synthesis of COMs in inter­stellar ices upon exposure to ioni­zi­ng radiation by exploiting a novel technology through the exploitation of tunable vacuum ultraviolet photo­ioni­zation as delivered from a synchrotron (Hefei).
