    "abstract": "The pair correlations in mesoscopic systems such as $nm$-size superconducting\nclusters and nuclei are studied at finite temperature for the canonical\nensemble of fermions in model spaces with a fixed particle number: i) a\ndegenerate spherical shell (strong coupling limit), ii) an equidistantly spaced\ndeformed shell (weak coupling limit). It is shown that after the destruction of\nthe pair correlations at T=0 by a strong magnetic field or rapid rotation,\nheating can bring them back. This phenomenon is a consequence of the fixed\nnumber of fermions in the canonical ensemble.",
