Sizable superconducting gap and anisotropic chiral topological superconductivity in the Weyl semimetal PtBi
Xiaochun Huang, Lingxiao Zhao, Sebastian Schimmel +5
Topological superconductors offer a fertile ground for realizing Majorana zero modes -- topologically protected, zero-energy quasiparticles that are resilient to local perturbation…
Temperature dependence of surface superconductivity in t-PtBi
Julia Besproswanny, Sebastian Schimmel, Yanina Fasano +5
The Weyl semimetal trigonal PtBi has recently been identified as a promising candidate material for intrinsic topological surface superconductivity emerging from the Fermi arc…
Direct probe of magnetic field effects on phonons by ultrasound propagation in a quasi-two-dimensional honeycomb magnet NaCoTeO
Xiaochen Hong, Maximilian Schiffer, Beat Valentin Schwarze +9
We study the phonon behavior of a Co-based honeycomb frustrated magnet NaCoTeO under magnetic field applied perpendicular to the honeycomb plane. The temperature and fi…
Bulk and surface electron scattering in disordered BiTe probed by quasiparticle interference
Vladislav Nagorkin, Sebastian Schimmel, Paul Gebauer +5
We investigated the electronic properties of the topological insulator BiTe by scanning tunneling microscopy and spectroscopy at low temperature. We obtained high-resol…
Fermi arcs dominating the electronic surface properties of trigonal PtBi
Sven Hoffmann, Sebastian Schimmel, Riccardo Vocaturo +10
Materials combining topologically non-trivial behavior and superconductivity offer a potential route for quantum computation. However, the set of available materials intrinsically…
Spinon heat transport in the three-dimensional quantum magnet PbCuTeO
Xiaochen Hong, Matthias Gillig, Abanoub R. N. Hanna +5
Quantum spin liquids (QSL) are novel phases of matter which remain quantum disordered even at the lowest temperature. They are characterized by emergent gauge fields and fractional…
