Chronological feed of everything captured from Max Roser.
A study of 4Hb-TaS₂ — a bulk transition-metal dichalcogenide polytype alternating 1T and 1H layers — reveals that lattice mismatch between these layers generates an emergent incommensurate potential analogous to a moiré effect in a 3D bulk material, a phenomenon previously overlooked in hybrid TMDs. STM measurements combined with DFT+DMFT calculations show that this incommensurability locally modulates interlayer distance, tuning hybridization and charge transfer to push the system into a doped Mott regime, where local moments become self-screened and produce a zero-bias resonance. Bulk superconductivity is found to compete directly with both the incommensurate landscape and the associated charge transfer, positioning incommensurate potentials as a key — and previously unrecognized — control parameter for correlated and unconventional superconducting phases in bulk layered materials.
