Towards Measuring Variations of Casimir Energy by a Superconducting Cavity
Towards Measuring Variations of Casimir Energy by a Superconducting Cavity
We consider a Casimir cavity, one plate of which is a thin superconducting film. We show that when the cavity is cooled below the critical temperature for the onset of superconductivity, the sharp variation (in the far infrared) of the reflection coefficient of the film engenders a variation in the …
