| Summary:
The observation of a superconducting phase, an intertwined insulating phase,
and a continuous transition between the two at a commensurate filling of
$nu=1$ in bilayers of twisted WSe$_2$ at $theta=3.65^0$ raises a number of
intriguing questions about the origin of this phenomenology. Here we report the
possibility of a displacement-field induced continuous transition between a
superconductor and a quantum spin-liquid Mott insulator at $nu=1$, starting
with a simplified three-orbital model of twisted WSe$_2$, including on-site,
nearest-neighbor density-density interactions, and a chiral-exchange
interaction, respectively. By employing parton mean-field theory, we discuss
the nature of these correlated insulators, their expected evolution with the
displacement-field, and their phenomenological properties.
