Spatially Inhomogeneous Competition between Superconductivity and the Charge Density Wave in YBa${}_2$Cu${}_3$O${}_{6.67}$

J. Choi, O. Ivashko, E. Blackburn +13

The charge density wave in the high-temperature superconductor YBa${}_2$Cu${}_3$O${}_{7-x}$ (YBCO) is now known to have two different ordering tendencies differentiated by their $c$-axis…
