“What do we measure when we put two bodies close to each other?”
11:00 AM – 12 Noon, Tuesday, November 29, 2022
Room No: 2000, Michigan Materials Research Institute,
2301 Bonisteel Blvd, Ann Arbor, MI 48109
Abstract: In this talk, we will present a summary of our experimental results of the measurements we have performed in the “Casimir regime”, i.e. when the separation
between bodies in thermal equilibrium is on the order of hundreds of nanometers, where retarded vacuum fluctuations are dominant. We will show our efforts to improve the precision of the measurements, perform the measurements in different engineered materials, and our general results for what is known to be “the search for a
fifth-force”. In this last topic, we will also show our current efforts to improve the limits in the search for exotic forces, dark matter, and dark energy. Finally, we will also present our plans to measure the friction, quantum in nature, when we move two bodies in relation to each other.
Bio: Ricardo Decca got his BS (1989) and Ph.D. (1994) in physics at the Instituto Balseiro in Argentina. In 2000 became an Assistant Professor of Physics at Indiana University-Purdue University Indianapolis. He is currently the Chair of the Department, co-director of the Nanoscale Imaging Center, and founding member of the Indiana University Center for Space Symmetries and the Center for Quantum Technologies. He is a fellow of the American Physical Society.
