    Single-electron charge transfer into putative Majorana and trivial modes in individual vortices

    Majorana bound states are putative collective excitations in solids that exhibit the self-conjugate property of Majorana fermions—they are their own antiparticles. In iron-based superconductors, zero-energy st...

    Puddle formation and persistent gaps across the non-mean-field breakdown of superconductivity in overdoped (Pb,Bi)2Sr2CuO6+δ

    The cuprate high-temperature superconductors exhibit many unexplained electronic phases, but the superconductivity at high do** is often believed to be governed by conventional mean-field Bardeen–Cooper–Schr...

    Spatially dispersing Yu-Shiba-Rusinov states in the unconventional superconductor FeTe0.55Se0.45

    By using scanning tunneling microscopy (STM) we find and characterize dispersive, energy-symmetric in-gap states in the iron-based superconductor FeTe0.55Se0.45, a material that exhibits signatures of topological...
