Observation of superconducting diode effect in antiferromagnetic Mott insulator $α$ -RuCl $_{3}$

Jiadian He, Yifan Ding, Xiaohui Zeng +15

Nonreciprocal superconductivity, also called as superconducting diode effect that spontaneously breaks time-reversal symmetry, is characterized by asymmetric critical currents unde…

Electron-phonon coupling and superconductivity in the doped topological-crystalline insulator (Pb $_{0.5}$ Sn $_{0.5}$ ) $_{1 - x}$ In $_{x}$ Te

A. Sapkota, Y. Li, B. L. Winn +12

We present a neutron scattering study of phonons in single crystals of (Pb $_{0.5}$ Sn $_{0.5}$ ) $_{1 - x}$ In $_{x}$ Te with $x = 0$ (metallic, but nonsuperconducting) and $x = 0.2$ (nonmetallic…

Evidence for singular-phonon-induced nematic superconductivity in a topological superconductor candidate Sr $_{0.1}$ Bi $_{2}$ Se $_{3}$

Jinghui Wang, Kejing Ran, Shichao Li +11

Superconductivity mediated by phonons is typically conventional, exhibiting a momentum-independent s-wave pairing function, due to the isotropic interactions between electrons and…

Unusual phonon density of states and response to the superconducting transition in the In-doped topological crystalline insulator Pb $_{0.5}$ Sn $_{0.5}$ Te

Kejing Ran, Ruidan Zhong, Tong Chen +13

We present inelastic neutron scattering results of phonons in (Pb $_{0.5}$ Sn $_{0.5}$ ) $_{1 - x}$ In $_{x}$ Te powders, with $x = 0$ and 0.3. The $x = 0$ sample is a topological crystalline insu…
