Abstract:
Precision atomic spectroscopy has played an important role in discovering new physics. Recent developments in spectroscopy tecniques utilizing novel methods have opened up new possibilities for precision measurements. These
techniques include the use of ultra-cold atoms by laser cooling and trapping, spectroscopy of trapped ions, development of stable lasers with ultra-narrow linewidths, and more recently, the application of femto-second laser-based frequency combs. In this talk, I will review some spectroscopic techniques and recent experimental examples using these methods to study fundamental physics. In particular, I will discuss (1) probing atomic nuclei, (2) determination of a fundamental constant and (3) testing the constancy of fundamental interactions. The physics motivation, current status, and future direction of these experiments will be discussed.
