Signatures of Amorphous Shiba State in FeTeSe
Jinwon Lee, Sanghun Lee, Andreas Kreisel +7
The iron-based superconductor FeTeSe is a peculiar material: it hosts a surface state with a Dirac dispersion, is a putative topological superconductor hosting Ma…
Puddle formation, persistent gaps, and non-mean-field breakdown of superconductivity in overdoped (Pb,Bi)2Sr2CuO6+δ
Willem O. Tromp, Tjerk Benschop, Jian-Feng Ge +14
The cuprate high-temperature superconductors exhibit many unexplained electronic phases, but it was often thought that the superconductivity at sufficiently high doping is governed…
Single-electron charge transfer into putative Majorana and trivial modes in individual vortices
Jian-Feng Ge, Koen M. Bastiaans, Damianos Chatzopoulos +6
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…
Direct evidence for Cooper pairing without a spectral gap in a disordered superconductor above
Koen M. Bastiaans, Damianos Chatzopoulos, Jian-Feng Ge +9
The idea that preformed Cooper pairs could exist in a superconductor above its zero-resistance state has been explored for unconventional, interface, and disordered superconductors…
Spatially dispersing Yu-Shiba-Rusinov states in the unconventional superconductor
Damianos Chatzopoulos, Doohee Cho, Koen M. Bastiaans +7
By using scanning tunneling microscopy (STM) we find and characterize dispersive, energy-symmetric in-gap states in the iron-based superconductor $\mathrm{FeTe}_{0.55}\mathrm{Se}_{…
Imaging doubled shot noise in a Josephson scanning tunneling microscope
K. M. Bastiaans, D. Cho, D. Chatzopoulos +3
We have imaged the current noise with atomic resolution in a Josephson scanning tunneling microscope with a Pb-Pb junction. By measuring the current noise as a function of applied…
A strongly inhomogeneous superfluid in an iron-based superconductor
D. Cho, K. M. Bastiaans, D. Chatzopoulos +2
Among the mysteries surrounding unconventional, strongly correlated superconductors is the possibility of spatial variations in their superfluid density. We use atomic-resolution J…
Amplifier for scanning tunneling microscopy at MHz frequencies
K. M. Bastiaans, T. Benschop, D. Chatzopoulos +4
Conventional scanning tunneling microscopy (STM) is limited to a bandwidth of circa 1kHz around DC. Here, we develop, build and test a novel amplifier circuit capable of measuring…
