We report on preliminary results on the measurement of variations of the Casimir energy in rigid cavities through its influence on the superconducting transition of in-cavity aluminium (Al) thin films. After a description of the experimental apparatus, we report on a measurement in the presence of thermal photons, discussing its implications for the zero-point photons case. Finally, we show preliminary results for the zero-point case.

Abstract
We report on preliminary results on the measurement of variations of the Casimir energy in rigid cavities through its influence on the superconducting transition of in-cavity aluminium (Al) thin films. After a description of the experimental apparatus, we report on a measurement in the presence of thermal photons, discussing its implications for the zero-point photons case. Finally, we show preliminary results for the zero-point case.| File | Dimensione | Formato | |
