Abstract

The recently demonstrated x-ray scattering approach using a free electron laser with a high field pulsed magnet has opened new opportunities to explore the charge-density-wave (CDW) order in cuprate high temperature superconductors. Using this approach, we substantially degrade the superconductivity with magnetic fields up to 33 T to investigate the onset of CDW order in YBa2Cu3Ox at low temperatures near a putative quantum critical point (QCP) at p1∼0.08 holes per Cu. We find no CDW can be detected in a sample with a doping concentration smaller than p1. Our results indicate that the onset of the CDW ground state lies inside the zero-field superconducting dome, and broken translational symmetry is associated with the putative QCP at p1.
