The authors use scanning tunneling spectroscopy to investigate the evolution of quasiparticle interference in a single-layer cuprate compound. They find evidence for an emergent normal fluid in the superconducting ground state of overdoped samples, with the gapless quasiparticles located at the antinodal region of reciprocal space.
