Quasiparticle Nernst effect in stripe-ordered cuprates
Experiments on underdoped cuprate superconductors suggest an intricate relation between the normal-state Nernst effect and stripe order: The Nernst signal appears enhanced near 1/8 hole doping and its onset temperature scales with the stripe-ordering temperature over some range of doping. Here, we employ a phenomenological quasiparticle model to calculate the normal-state Nernst signal in the p...
متن کاملStripe order and quasiparticle Nernst effect in cuprate superconductors
After a brief review of current ideas on stripe order in cuprate high-temperature superconductors, we discuss the quasiparticle Nernst effect in cuprates, with focus on its evolution in non-superconducting stripe and related nematic states. In general, we find the Nernst signal to be strongly enhanced by nearby van-Hove singularities and Lifshitz transitions in the band structure, implying that...
متن کاملNernst effect in the electron-doped cuprates
We calculate the normal state Nernst signal in the cuprates resulting from a reconstruction of the Fermi surface due to spin density wave order. An order parameter consistent with the reconstruction of the Fermi surface detected in electron-doped materials is shown to sharply enhance the Nernst signal close to optimal doping. Within a semiclassical treatment, the obtained magnitude and position...
متن کاملBerry phase mechanism for optical gyrotropy in stripe-ordered cuprates
Optical gyrotropy, the lifting of degeneracy between left and right circularly polarized light, can be generated by either time-reversal or chiral symmetry breaking. In the high-Tc superconductor La2−xBaxCuO4 (LBCO), gyrotropy onsets at the same temperature as charge stripe order, suggesting that the rotation of the stripe direction from one plane to the next generates a helical pattern that br...
متن کاملStripe ordering in the Cuprates
Upon cooling, many materials undergo an electronic phase transition leading to infinite conductivity. This state of matter, known as superconductivity, was first discovered in 1911 by Kamerlingh Onnes while working with liquefied helium [Onnes]. At 4.2K he discovered that the resistivity of mercury dropped below detectable values. Shortly after this discovery, many other elements, such as tin, ...
