Effect of quasiparticle damping on the properties of high-Tc superconductors
Zverev V. M., Silin V. P.
An analytic expression describing the effect of quasiparticle damping on the superconducting transition temperature is derived from the Eliashberg equations. This damping is important for determining Tc and the ratio 2Д0/ТС for such superconductors as Bi2Sr2CaCu208 and YBa2Cu307.
