Pinning of dynamic spin-density-wave fluctuations in cuprate superconductors
We present a theory of the pinning of dynamic spin-density-wave ~SDW! fluctuations in a d-wave superconductor by local imperfections that preserve spin-rotation invariance, such as impurities or vortex cores. The pinning leads to static spatial modulations in spin-singlet observables, while the SDW correlations remain dynamic: these are the ‘‘Friedel oscillations’’ of a spin-gap antiferromagnet...
متن کاملComplementary pair-density-wave and d-wave-checkerboard orderings in high-temperature superconductors
The competing orders in the particle-particle P-P channel and the particle-hole P-H channel have been proposed separately to explain the pseudogap physics in cuprates. By solving the Bogoliubov-de Gennes equation self-consistently, we show that there is a general complementary connection between the d-wave-checkerboard DWCB order in the P-H channel and the pair-density-wave PDW order in the P-P...
متن کاملPair density wave in the pseudogap state of high temperature superconductors.
Recent scanning tunneling microscopy experiments of Bi(2)Sr(2)CaCu(2)O(8+delta) have shown evidence of real-space organization of electronic states at low energies in the pseudogap state [Science 303, 1995 (2004)]]. We argue based on symmetry considerations as well as model calculations that the experimentally observed modulations are due to a density wave of d-wave Cooper pairs without global ...

We present a theory of the pinning of dynamic spin density wave (SDW) fluctuations in a d-wave superconductor by local imperfections which preserve spin-rotation invariance, such as impurities or vortex cores.

متن کاملEffect of thermal fluctuations in topological p-wave superconductors
We study the effect of thermal fluctuations on the topological stability of chiral p-wave superconductors. We consider two models of superconductors: spinless and spinful with a focus on topological properties and Majorana zero-energy modes. We show that proliferation of vortex-antivortex pairs above the Kosterlitz-Thouless temperature TKT drives the transition from a thermal Quantum Hall insul...
