    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 ...
