Bridging atomic and mesoscopic length scales with Replica Scanning Tunneling Microscopy: Visualizing the atomic lattice of UTe and the atomic scale superconducting gap modulations of FeSe close to micron length scales
Miguel Ãgueda Velasco, Miguel Águeda Velasco, Jose D. Bermúdez-Pérez +21
Scanning Tunneling Microscopy is a cornerstone technique for visualizing the electronic density of states with atomic resolution (typically below 0.1 nm). While the field of view o…
Robust two-dimensional surface superconductivity and vortex lattice in the Weyl semimetal -PtBi
Jose Antonio Moreno, Pablo García Talavera, Pablo GarcÃa Talavera +11
The layered compound -PtBi is a topological semimetal with Fermi arcs at the surface joining bulk Weyl points. Recent work has found signatures of surface superconductivity…
Direct observation of vortex liquid droplets in the iron pnictide superconductor CaKAsFe at _c$
Oscar Bou Marqués, Oscar Bou Marqués, Jose A. Moreno +10
Type-II superconductors under magnetic fields are in a quantum coherent non-dissipative state as long as vortices remain pinned. Dissipation appears when vortices depin, eventually…
Superconducting density of states of PtPb4
Pablo GarcÃa Talavera, Jose Antonio Moreno, Edwin Herrera +5
PtPb is a type II superconductor with a bulk critical temperature K and an upper critical field of T. PtPb is related to non-superconducting…
Role of Nematic Fluctuations on Superconductivity in FeSeTe Revealed by NMR under Pressure
Qing-Ping Ding, Juan Schmidt, Jose A. Moreno +3
The relationship between antiferromagnetic (AFM) spin fluctuations (SF), nematic fluctuations, and superconductivity (SC) has been central to understanding the pairing mechanism in…
