Universal quasiparticle decoherence in hole- and electron-doped high-Tc cuprates

Z. -H. Pan, P. Richard, A. V. Fedorov +8

We use angle-resolved photoemission to unravel the quasiparticle decoherence process in the high-$T_c$ cuprates. The coherent band is highly renormalized, and the incoherent part m…
