Electronic structure of topological defects in the pair density wave superconductor
arXiv:2406.03538 · doi:10.1103/PhysRevB.110.214508
Abstract
Pair density waves (PDWs) are a inhomogeneous superconducting states whose Cooper pairs possess a finite momentum resulting in a oscillatory gap in space, even in the absence of an external magnetic field. There is growing evidence for the existence of PDW superconducting order in many strongly correlated materials, particularly in the cuprate superconductors and in several other different types of systems. A feature of the PDW state is that inherently it has a CDW as a composite order associated with it. Here we study the structure of the electronic topological defects of the PDW, paying special attention to the half-vortex and its electronic structure that can be detected in STM experiments. We discuss tell-tale signatures of the defects in violations of inversion symmetry, in the excitation spectrum and their spectral functions in the presence of topological defects. We discuss the ``Fermi surface'' topology of Bogoliubov quasiparticle of the PDW phases, and we briefly discuss the role of quasiparticle interference.
arXiv commentA few editorial edits were updated as well as some acknowledgments. A couple minus signs were also missing in equation 3.13 and 3.14. Finally, the orthogonal matrix after equation B.5 needed to be updated. A few references were also updated or removed
