Enhanced Condensation Through Rotation

Abstract

We argue that rotation of a thin superconducting cylinder can increase the critical superconducting temperature substantially. A purely rotational effect originates from the tendency of a steadily rotating mechanical system to maximize its moment of inertia. A condensation of Cooper pairs in a rotating cylinder decouples a part of the normal electron fraction from rotation, thus producing a circulating electric current of an uncompensated electric charge of lattice ions. The current generates the magnetic field that stores energy of rotation, thus increasing the moment of inertia. In the presence of an external magnetic field, another enhancement effect originates from the interaction energy of the dipole magnetic moment of the normal component with the background magnetic field. In both cases, rotation of the cylindrical shell promotes the formation of condensate that decouples from mechanical rotation. We give quantitative estimates for a thin cylinder of aluminum.
