Superconductivity in W <sub>3</sub> Re <sub>2</sub> C with Chiral Structure
We discover superconductivity in cubic W<sub>3</sub>Re<sub>2</sub>C with chiral structure, and the superconducting transition temperature <i>T</i><sub>c</sub> is about 6.2 K. Detailed characterizations and analysis indicate that W<sub>3</sub>Re<sub>2</sub>C is a bulk type-II BCS superconductor with a fully isotropic gap. Moreover, first-principles calculations indicate that electron-phonon coupling primarily arises from interactions between W/Re 5<i>d</i> electronic states and their low-frequency phonons. Furthermore, the breaking of the inversion symmetry in W<sub>3</sub>Re<sub>2</sub>C facilitates the emergence of Weyl points in the electronic structure. Therefore, W<sub>3</sub>Re<sub>2</sub>C can serve as a promising platform for investigating the influences of the chiral structure on both superconductivity and band topology.
