    "abstract": "We consider a Casimir cavity, one plate of which is a thin superconducting\nfilm. We show that when the cavity is cooled below the critical temperature for\nthe onset of superconductivity, the sharp variation (in the far infrared) of\nthe reflection coefficient of the film engenders a variation in the value of\nthe Casimir energy. Even though the relative variation in the Casimir energy is\nvery small, its magnitude can be comparable to the condensation energy of the\nsuperconducting film, and this gives rise to a number of testable effects,\nincluding a significant increase in the value of the critical magnetic field,\nrequired to destroy the superconductivity of the film. The theoretical ground\nis therefore prepared for the first experiment ever aimed at measuring\nvariations of the Casimir energy itself.",
