Title: An optically-driven macroscopic cantilever
Abstract: I will report an interferometric experiment to detect optically-driven resonance on a macroscopic object. Utilizing dynamic force microscopy, the resonant motion of a cm-sized cantilever driven by an amplitude-modulated laser is directly observed. I will also discuss other experimental techniques underway in our research lab and their potential applications to precision measurements such as tests of short-range gravity.
