The influence of these orders on the coexisting superconductivity remains an important issue, and low-temperature thermal conductivity measurements can be a powerful probe of the relevant low-energy quasiparticles deep in the superconducting state. To this end, we will present new dilution-fridge-temperature thermal conductivity measurements as a function of magnetic field on underdoped Hg1223 (for Tc = 78 K and 112 K) as well as the related single-layer cuprate Hg1201 (HgBa2CuO6+δ, for Tc = 74 K), along with comparison to other cuprates.
