Direct probe of magnetic field effects on phonons by ultrasound propagation in a quasi-two-dimensional honeycomb magnet Na $_{2}$ Co $_{2}$ TeO $_{6}$

Xiaochen Hong, Maximilian Schiffer, Beat Valentin Schwarze +9

We study the phonon behavior of a Co-based honeycomb frustrated magnet Na $_{2}$ Co $_{2}$ TeO $_{6}$ under magnetic field applied perpendicular to the honeycomb plane. The temperature and fi…

Sizable superconducting gap and anisotropic chiral topological superconductivity in the Weyl semimetal PtBi $_{2}$

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 $_{2}$

Julia Besproswanny, Sebastian Schimmel, Yanina Fasano +5

The Weyl semimetal trigonal PtBi $_{2}$ has recently been identified as a promising candidate material for intrinsic topological surface superconductivity emerging from the Fermi arc…
