1T-TaS2 as a quantum spin liquid
1T-TaS2 is unique among transition metal dichalcogenides in that it is understood to be a
correlation-driven insulator, where the unpaired electron in a 13-site cluster experiences …

Unconventional Fermi surface in an insulating state
Insulators occur in more than one guise; a recent finding was a class of topological
insulators, which host a conducting surface juxtaposed with an insulating bulk. Here, we …
