Method for Operating a Superconductor at a Temperature Higher than the Superconductive Temperature Tc

摘要

A method of operating a superconductor in its superconductivity state at a temperature Tc(i) in the range of T_c* to T_c, where T_c* is greater than the superconductivity temperature T_c of the superconductor, includes cooling the superconductor to a temperature of T_c or less and applying energy to the superconductor after the superconductor has entered a superconducting state. The energy corresponds to the quantum energy hv in the range of a minimum energy less than E₀ to less than E₀, where E₀ is the ground state of the two-dimensional excitation binding energy of the superconductor The superconductor is then cooled to the selected temperature T_c(i). The minimum energy is 8/9 of E₀.
