Open AccessMagnetotransport signatures of antiferromagnetism coexisting with charge order in the trilayer cuprate HgBa2Ca2Cu3O8+δ
Multilayered cuprates possess not only the highest superconducting temperature transition but also offer a unique platform to study disorder-free CuO2 planes and the interplay between competing orders with superc...

Universal T-linear resistivity and Planckian dissipation in overdoped cuprates
The perfectly linear temperature dependence of the electrical resistivity observed as T → 0 in a variety of metals close to a quantum critical point1–4 is a major puzzle of condensed-matter physics5. Here we show...

Change of carrier density at the pseudogap critical point of a cuprate superconductor
Low-temperature measurements of the Hall effect in cuprate materials in which superconductivity is suppressed by high magnetic fields show that the pseudogap is not related to the charge ordering that has been...

Open AccessEvidence for a small hole pocket in the Fermi surface of underdoped YBa2Cu3Oy
In underdoped cuprate superconductors, the Fermi surface undergoes a reconstruction that produces a small electron pocket, but whether there is another, as yet, undetected portion to the Fermi surface is unkno...

Open AccessDirect measurement of the upper critical field in cuprate superconductors
In the quest to increase the critical temperature Tc of cuprate superconductors, it is essential to identify the factors that limit the strength of superconductivity. The upper critical field Hc2 is a fundamental...

Quantum oscillations in an overdoped high-Tc superconductor
As well as their elevated superconducting transition temperatures (Tcs), the copper-oxide superconductors display a variety of novel physical properties that have inspired many theories to explain their electroni...

Two energy scales in the spin excitations of the high-temperature superconductor La2−xSrxCuO4
The excitations responsible for producing high-temperature superconductivity in the copper oxides have yet to be identified. Two promising candidates are collective spin excitations and phonons1. A recent argumen...
