Anisotropy of the Seebeck Coefficient in the Cuprate Superconductor YBa${}_2$Cu${}_3$O${}_y$: Fermi-Surface Reconstruction by Bidirectional Charge Order

O. Cyr-Choinière, S. Badoux, G. Grissonnanche +11

The Seebeck coefficient $S$ of the cuprate YBa${}_2$Cu${}_3$O${}_y$ was measured in magnetic fields large enough to suppress superconductivity, at hole dopings $p=0.11$ and $p =…
