Anomalously high quasiparticle thermal conductivity in the underdoped cuprate superconductor HgBa${}_2$CuO${}_{4+\delta }$

Jordan Baglo, Quentin Barthélemy, Étienne Lefrançois +4

The single-layer cuprate superconductor HgBa${}_2$CuO${}_{4+\delta }$ (Hg1201) is an ideal candidate for investigating many properties of cuprates with minimal disorder and without the com…
