Abstract The interplay between electron correlation and topology of relativistic electrons may lead to a fascinating stage of the research on quantum materials and emergent functions. The emergence of various collective electronic orderings/liquids,

Electron correlation normally makes electrons less mobile, but it is still not clear when correlation becomes very strong in Dirac semimetals. Here, Fujioka et al. report a very high electron mobility exceeding 60,000 cm2V−1s−1 in correlated Dira

Abstract Ferroelectric polarization and metallic conduction are two seemingly irreconcilable properties that cannot normally coexist in a single system, as the latter tends to screen the former. Polar metals, however, defy this rule and have thus att

Chirality affects many properties of materials, but how it affects superconductivity remains unclear. Here, Qinet al. report nonreciprocal supercurrent flows in individual nanotubes of WS2via ionic gating, evidencing chiral superconducting transport.

Thermoelectric energy conversion is one of the most important applications of functional materials for energy. To realize practical applications, high conversion efficiency is required over a wide range of temperatures. Furthermore, abundance as well
