Precision measurements with atoms and molecules: atomic clocks and fundamental symmetries.

August 14, 2015 - 12:00am
Speaker: 
Jiehang Zhang

Precision measurements lie deep in the heart of atomic physics. The SI unit of time is defined by counting the oscillations of a microwave transition in Cs atoms. Modern optical atomic clocks are demonstrating stabilities and accuracies beyond the Cs standard. Certain frequency measurements can also test fundamental symmetries and place constraints on beyond Standard Model physics. These include Lorentz symmetry, time reversal symmetry, and parity violation. I will give a general overview of how atomic physics experiments performed with table-top platforms can give limits that are complementary to high energy physics experiments.
