  Twisted van der Waals heterostructures have latterly received prominent
attention for their many remarkable experimental properties, and the promise
that they hold for realising elusive states of matter in the laboratory. We
propose that these systems can, in fact, be used as a robust quantum simulation
platform that enables the study of strongly correlated physics and topology in
quantum materials. Among the features that make these materials a versatile
toolbox are the tunability of their properties through readily accessible
external parameters such as gating, straining, packing and twist angle; the
feasibility to realize and control a large number of fundamental many-body
quantum models relevant in the field of condensed-matter physics; and finally,
the availability of experimental readout protocols that directly map their rich
phase diagrams in and out of equilibrium. This general framework makes it
possible to robustly realize and functionalize new phases of matter in a
modular fashion, thus broadening the landscape of accessible physics and
holding promise for future technological applications.
