Charge order in the pseudogap phase of cuprate superconductors
Charge ordering instabilities are studied in amultiorbitalmodel of cuprate superconductors. A known, key feature of thismodel is that the large local Coulomb interaction in theCu − dx y 2 2 orbitals generates localmoments with short range antiferromagnetic (AF) correlations. The strong simplifying ansatz that thesemoments are static and ordered allows us to explore a regime not generally access...
متن کاملModel of quasiparticles coupled to a frequency-dependent charge-density-wave order parameter in cuprate superconductors.
We investigate a model where superconducting electrons are coupled to a frequency dependent charge-density wave order parameter Delta_{r}(omega). Our approach can reconcile the simultaneous existence of low-energy Bogoljubov quasiparticles and high energy electronic order as observed in scanning tunneling microscopy (STM) experiments. The theory accounts for the contrast reversal in the STM spe...
متن کاملMagnetic Field Tuning of Charge and Spin Order in the Cuprate Superconductors
Recent neutron scattering, nuclear magnetic resonance, and scanning tunneling microscopy experiments have yielded valuable new information on the interplay between charge and spin density wave order and superconductivity in the cuprate superconductors, by using an applied perpendicular magnetic field to tune the ground state properties. We compare the results of these experiments with the predi...
متن کاملCharge Dynamics in Cuprate Superconductors
In this lecture we present some interesting issues that arise when the dynamics of the charge carriers in the CuO2 planes of the high temperature superconductors is considered. Based on the qualitative picture of doping, set by experiments and some previous calculations, we consider the strength of various inter and intra-cell charge transfer susceptibilities, the question of Coulomb screening ...
متن کاملCollective modes and quasiparticle interference on the local density of states of cuprate superconductors
The energy, momentum, and temperature dependence of the quasiparticle local density of states ~LDOS! of a two-dimensional dx22y2-wave superconductor with random disorder is investigated using the first-order T-matrix approximation. The results suggest that collective modes such as spin-charge-density waves are relevant low-energy excitations of the cuprates that contribute to the observed LDOS ...
