- W4380716078 abstract "Majorana zero modes form as intrinsic defects in an odd-orbital one-dimensional superconductor, thus motivating the search for such materials in the pursuit of Majorana physics. Here, we present combined experimental results and first-principles calculations which suggest that quasi-one-dimensional ${mathrm{K}}_{2}{mathrm{Cr}}_{3}{mathrm{As}}_{3}$ may be such a superconductor. Using inelastic neutron scattering we probe the dynamic spin susceptibilities of ${mathrm{K}}_{2}{mathrm{Cr}}_{3}{mathrm{As}}_{3}$ and ${mathrm{K}}_{2}{mathrm{Mo}}_{3}{mathrm{As}}_{3}$ and show the presence of antiferromagnetic spin fluctuations in both compounds. Below the superconducting transition, these fluctuations gap in ${mathrm{K}}_{2}{mathrm{Mo}}_{3}{mathrm{As}}_{3}$ but not in ${mathrm{K}}_{2}{mathrm{Cr}}_{3}{mathrm{As}}_{3}$. Using first-principles calculations, we show that these fluctuations likely arise from nesting on one-dimensional features of the Fermi surface. Considering these results we propose that while ${mathrm{K}}_{2}{mathrm{Mo}}_{3}{mathrm{As}}_{3}$ is a conventional superconductor, ${mathrm{K}}_{2}{mathrm{Cr}}_{3}{mathrm{As}}_{3}$ is likely a spin triplet, and consequently a topological superconductor." @default.
