Open AccessHigh-field immiscibility of electrons belonging to adjacent twinned bismuth crystals
Bulk bismuth has a complex Landau spectrum. The small effective masses and the large g-factors are anisotropic. The chemical potential drifts at high magnetic fields. Moreover, twin boundaries further complexi...

Open AccessUnidirectional Kondo scattering in layered NbS2
Crystalline defects can modify quantum interactions in solids, causing unintuitive, even favourable, properties such as quantum Hall effect or superconducting vortex pinning. Here we present another example of...

Hidden magnetism at the pseudogap critical point of a cuprate superconductor
The nature of the pseudogap phase of hole-doped cuprate superconductors is still not understood fully. Several experiments have suggested that this phase ends at a critical hole do** level p*, but the nature of...

Open AccessQuantum-dot assisted spectroscopy of degeneracy-lifted Landau levels in graphene
Energy spectroscopy of strongly interacting phases requires probes which minimize screening while retaining spectral resolution and local sensitivity. Here, we demonstrate that such probes can be realized usin...

Open AccessHigh field charge order across the phase diagram of YBa2Cu3Oy
In hole-doped cuprates there is now compelling evidence that inside the pseudogap phase, charge order breaks translational symmetry. In YBa2Cu3O y charge order emerges in two st...

Thermodynamic phase diagram of static charge order in underdoped YBa2Cu3Oy
A thermodynamic probe of the recently discovered charge-density-wave order in YBa2Cu3Oy reveals a biaxial modulation in magnetic fields up to 40 T.

Broken rotational symmetry in the pseudogap phase of a high-Tc superconductor
Knowledge of the nature of the pseudogap phase is critical to understanding the properties of high-transition-temperature (high-Tc) copper oxide superconductors. A fundamental question is what symmetries are brok...

Enhancement of the Nernst effect by stripe order in a high-Tc superconductor
The Nernst effect in metals is highly sensitive to two kinds of phase transition: superconductivity and density-wave order. The large positive Nernst signal observed in hole-doped high-Tc superconductors above th...

Linear temperature dependence of resistivity and change in the Fermi surface at the pseudogap critical point of a high-Tc superconductor
Transport measurements in a high-temperature superconductor provide evidence that the so-called pseudogap phase ends at a quantum critical point located inside the superconducting dome in the phase diagram of ...

Electron pockets in the Fermi surface of hole-doped high-Tc superconductors
A recent paper (Nature 447, 565—568 2007) described the electronic structure of a hole–doped high–temperature copper oxide superconductor in its normal metallic state. The Fermi surface observed in underdoped mat...

Quantum oscillations and the Fermi surface in an underdoped high-Tc superconductor
Two papers in this issue report notable contributions towards an understanding of high-temperature superconductivity, still an elusive goal after more than 20 years of intensive research. Doiron-Leyraud et al. re...
