TL;DR: The observation of charge-density-wave correlations in the model cuprate superconductor HgBa2CuO(4+δ) (T(c)=72 K) via bulk Cu L3-edge-resonant X-ray scattering points to a unifying picture in which these two phenomena are preceded at the higher pseudogap temperature by q=0 magnetic order and the build-up of significant dynamic antiferromagnetic correlations.

TL;DR: This work demonstrates for the quintessential compound HgBa2CuO4+δ a dramatic switch from linear to purely quadratic (Fermi liquid-like, ρ ∝ T2) resistive behavior in the pseudogap regime and reveals the fundamental resistance per copper–oxygen sheet.

TL;DR: In this paper, it was shown that quantum oscillations are a universal property of the underdoped CuO2 planes, and it opens the door to quantitative future studies of the metallic state and of the Fermi-surface reconstruction phenomenon in this structurally simplest cuprate.

TL;DR: In this article, it was shown that the near-nodal excitations of underdoped cuprates obey Fermi liquid behavior, where the lifetime τ(ω, T) of a quasiparticle depends on its energy ω as well as on the temperature T.

TL;DR: In-plane resistivity and transverse magnetoresistance measurements for underdoped HgBa(2)CuO(4+δ) (Hg1201) show a quadratic field dependence, and it is shown that this behavior is typically masked in cuprates with lower structural symmetry or strong disorder effects.
