Coherent quasiparticle weight and its connection to high-T_c superconductivity from angle-resolved photoemission

H. Ding, J. R. Engelbrecht, Z. Wang +7

In conventional superconductors, the pairing energy gap (Δ) and superconducting phase coherence go hand-in-hand. As the temperature is lowered, both the energy gap and phase cohere…
