Explore the cutting-edge research on the thermal Casimir effect in this 23-minute conference talk from the Workshop on "Blackbody Radiation Induced Effects and Phenomena" at the Erwin Schrödinger International Institute for Mathematics and Physics. Delve into the fascinating world of quantum effects manifesting as forces between macroscopic objects, with a focus on the less-studied contribution of thermal photons. Learn about the CANNEX setup, a unique metrological force measurement device capable of detecting Casimir forces between plane-parallel plates in the thermal regime out of equilibrium. Discover how this groundbreaking research allows for the first quantitative detection of the anti-symmetric contribution and thermal radiation pressure in Casimir forces. Gain insights into the current status of thermal Casimir force measurements, the capabilities of CANNEX, and the exciting results expected in the coming years.
