Estimating many-body effects that deviate from an independent particle approach has long been a key research interest in condensed matter physics. Layered cuprates are prototypical systems, where electron-electron interactions are found to strongly a

The origin of the Fermi surface reconstruction that occurs in cuprate superconductors as hole doping increases remains unclear. Here, the authors observe long range charge density wave (CDW) order in the overdoped single-layer cuprate Tl2Ba2CuO6+δ ,

Sr3Ru2O7 exhibits a quantum critical point tunable by magnetic field and has been widely used in the study of criticality. Here, by using inelastic neutron scattering, the authors measure collective magnetic excitations near the quantum critical poin

Inelastic neutron scattering is used to study the magnetic excitations of the S=1 square-lattice antiferromagnet La_{2}NiO_{4}. We find that the spin waves cannot be described by a simple classical (harmonic) Heisenberg model with only nearest-neighb

Magnetic field induced competing phases in high-temperature superconductors provide a testbed for various theoretical scenarios. Here, Choi et al. report evidence of inhomogeneous superconducting state due to the different competition strength betwee

Many predicted topological quasi-particles still await experimental discovery. Here, Horio et al. reveal the existence of two-dimensional type-II Dirac fermions in the high-temperature superconductor La1.77Sr0.23CuO4, promoting layered oxides as prom

The interplay between competing orders in high-temperature superconductors can be tuned by the application of magnetic fields. Here, Chang et al. report high field induced three-dimensional charge density wave in underdoped YBa2Cu3O6.67, which sugges

Theories of the origin of superconductivity in cuprates are dependent on an understanding of their normal state which exhibits various competing orders. Transport and thermodynamic measurements on La$_{2-x}$Sr$_x$CuO$_4$ show signatures of a quantum
