An energy scale directly related to superconductivity in the high-$T_c$ cuprate superconductors: Universality from the Fermi arc picture

S. Ideta, T. Yoshida, A. Fujimori +10

We have performed a temperature dependent angle-resolved photoemission spectroscopy (ARPES) study of the tri-layer high-$T_c$ cuprate superconductor (HTSC) Bi${}_2$Sr${}_2$Ca${}_2$Cu${}_3$…
