Photoinduced Superconductivity in Cuprates

Anuj Nuwal, S. L. Kakani and M. L. Kalra

The photoinduced superconducting phase transition temperature in high-TC cuprates with two band Hamiltonian has been investigated. It is shown to possess two superconducting gaps. The superconductivity is caused by the interband repulsive electron-lattice and coulomb interaction. The photo- excitation produces a change of the hole doping (p) and as a result, the shift ΔTC of TC. The study of free energy, critical field and electronic specific heat based on this model is also presented.
