Bounding the Pseudogap in Cuprate High-TC Superconductors

Scientists of the NHMFL-PFF have employed Resonant Ultrasound Spectroscopy to reveal a thermodynamic signature of the “Pseudo-Gap” within and beyond the superconducting phase boundary of YBCO. This experiment provides thermodynamic evidence that the pseudo gap is connected to the superconducting ground state in the cuprate materials.
