Description

I will discuss experimental aspects of new physics searches with cold atoms. The focus will be on Rydberg states of cold hydrogen and deuterium atoms and their application to searches for additional ``fifth forces’’ [1,2]. In particular, I will explore the experimental challenge of realizing cold, trapped samples of hydrogen and deuterium [3,4] and some possible solutions. I will also consider experiments involving entangled atomic clocks in a gravitational potential that pose a challenge to the framework of general relativity.
