Condensed Matter Seminar: "Quantum Criticality in High Temperature Superconducting Cuprates"
Anomalous transport behavior in near-optimally-doped high temperature superconducting cuprates has been linked to fluctuations associated with a quantum critical point. Using resonant ultrasound spectroscopy we find evidence for a phase boundary inside the superconducting dome in the temperature-doping phase diagram of YBCO cuprates. This suggests a quantum critical point near optimal doping that is hidden by superconductivity.
