We normally think of large accelerators and massive detectors when we consider the frontiers of elementary particle physics, pushing to understand the universe at higher and higher energy scales. However, several tabletop low-energy experiments are positioned to discover a wide range of new physics beyond the Standard model, where feeble interactions require precision measurements rather than high energies. In high vacuum, optically levitated dielectric nanospheres achieve excellent decoupling from their environment, making force sensing at the zeptonewton level (10-21 N) achievable.
In this talk, I will describe our progress towards using these sensors for tests of the Newtonian gravitational inverse square law at micron-length scales. Optically levitated dielectric objects and optical cavities show promise for a variety of other applications, including searches for gravitational waves and dark matter. Finally, I will discuss the Axion Resonant InterAction Detection Experiment (ARIADNE), a precision magnetometry experiment using laser-polarized 3-He gas to search for a notable dark-matter candidate: the QCD axion.
Join the Queer Resource Center, the Center for Diversity and Student Leadership, and the Center for International Student Experience for an engaging talk given by Bamby Salcedo, a nationally and internationally recognized activist who has received numerous awards for her advocacy work in the trans and queer immigrant communities. Following the talk, there will be dinner and discussion.
