Abstract
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 enough correlation
to form a Mott insulator. We argue, based on existing data,
that this well-known material should be considered as a quantum
spin liquid, either a fully gapped Z2 spin liquid or a Dirac spin liquid.
We discuss the exotic states that emerge upon doping and
propose further experimental probes. Keywords: spin liquid; Mott insulator; transition metal dichalcogenide
