## Description

- description: Twisted bilayers of transition metal dichalcogenide semiconductors
    have enabled the discovery of superconductivity, ferromagnetism, correlated insulators
    and a series of new topological phases of matter. However, the connection between
    these electronic phases and the underlying band structure singularities in these
    materials has remained largely unexplored. Here, combining the magnetic circular
    dichroism and electronic compressibility measurements, we investigate the influence
    of a van Hove singularity on the correlated phases in bilayer WSe2 with twist
    angle between 2-3 degrees. We demonstrate stabilizing the Stoner ferromagnetism
    below moiré lattice filling one and Chern insulators at filling one by tuning
    the van Hove singularity cross the Fermi level using the electric and magnetic
    fields. The experimental observations are supported by the continuum model band
    structure calculations. Our results highlight the prospect of engineering the
    electronic phases by tunable van Hove singularities.
