Title: The Effect of the Earth's Gravity and Rotation on the Quantum Mechanical Phase of the Neutron

Speaker: Sam Werner of the NIST Neutron Physics Group

Abstract: Does Einstein's principle of equivalence of inertial and gravitational masses apply in the quantum limit? This question was posed and experimentally addressed in the neutron interferometry experiment of Colella, Overhauser and Werner (COW) in 1975. I will discuss this and subsequent versions and extensions of this experiment, and how they impact the recent controversy related to the gravitational redshift and Compton frequency in atomic-beam interferometry.
