Abstract: Broken symmetry in the pseudogap phase 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 broken when that phase sets in below a certain temperature, T*. Daou et al. report the observation of a large in-plane anisotropy of the Nernst effect in YBa2Cu3Oy that sets in precisely at T*, throughout the doping phase diagram. They show that the CuO chains of the orthorhombic lattice are not responsible for this anisotropy, which is therefore an intrinsic property of the CuO2 planes. They conclude that the pseudogap phase is an electronic state that strongly breaks fourfold rotational symmetry. This narrows the range of possible states considerably, pointing to stripe or nematic order.
