CAREER: Equivalence Principle Test with Ytterbium Atom Interferometry — NSF Award to Johns Hopkins University (MD, $431,961)
The equivalence principle (EP) states that all massive objects fall at the same rate in a given gravitational field. This idea can be tested by measuring the difference in acceleration of two freely falling objects. Since the EP is the foundation of general relativity, our most precise theory of gravity, EP tests probe

| Abstract | The equivalence principle (EP) states that all massive objects fall at the same rate in a given gravitational field. This idea can be tested by measuring the difference in acceleration of two freely falling objects. Since the EP is the foundation of general relativity, our most precise theory of gravity, EP tests probe the relationship between gravity and the other fundamental forces. In addition, EP tests are sensitive to the existence of new particles that could comprise “dark matter,” the mat |
