✦ Synopsis
Expressions of the transition temperature for various anomalous phases are first derived in the framework of the two-band model for copper oxides. The effects of the photon field for the model are discussed under the Thomas᎐Fermi approximation.
Possible other mechanisms and other systems for the photo-induced superconductivity are also examined theoretically. We also point out the possibilities of the photo-induced superconductivity in a Little model. Possible model systems of the tunable superconductivity by external fields are proposed as an example of dynamic controls of electronic, magnetic, and optical properties of materials.
