Unusual Quasiparticle Tunneling in High-$T_c$ Cuprate Superconductors: Evidence for the BCS and Polaronic Multi-Gap Effects on Tunneling Spectra

S. Dzhumanov, O. K. Ganiev, Sh. S. Djumanov

We propose a model of quasiparticle tunneling across the high-$T_c$ superconductor-insulator-normal metal junction based on the different mechanisms for tunneling of electrons at p…
