  Title: Optically Probing Nuclei Trapped in Cryogenic Solids:
Opportunities for Nuclear Physics
  Speaker: Prof. Jaideep Singh
  Institute: NSCL, Michigan State University
  Date: Monday, March 30, 2015
  Time: 4:00 - 5:00 pm EST
  Place: Nieuwland Science Hall, Room 124

  Abstract:

Inert gases frozen at cryogenic temperatures have been used to trap and study atoms and molecules for over 60 years. In particular, thin films of noble gas solids (NGS) are a promising medium for the capture, detection, and manipulation of atoms and nuclear spins. They provide stable, chemically inert, and efficient confinement for a wide variety of guest species. Because NGS are transparent at optical wavelengths, the guest species can be probed using lasers. Longitudinal and transverse nuclear spin relaxation times of a guest species can be made very long under well-understood and feasible conditions. Potential applications include measurements of rare nuclear reactions, long-term memory for quantum information processing, and tests of fundamental symmetries.
In this talk, I will summarize the results of our optical spectroscopic study of ytterbium atoms embedded in a frozen neon matrix, which was performed at Argonne National Lab. Furthermore, I will describe the planned activities of my new group at the NSCL at MSU, which includes the demonstration of optical single atom detection in-medium and the measurement of spin relaxation times of trapped nuclei. Our eventual goals are (1) to use single atom detection to measure the 22Ne(α,η)25Mg & 22Ne(α,γ)26Mg nuclear reactions, which are important for the s-process in stellar nucleosynthesis, and (2) to search for the permanent electric dipole moments of pear-shaped nuclei such as 225Ra and 229Pa, which have an enhanced sensitivity to time-reversal & parity violating interactions originating within nuclei.
