Abstract
Twisted tungsten diselenide bilayers host a variety of competing strongly correlated states, which can be understood from a Hubbard model on the moir\'e scale. Examples include coupled spin- and charge-density waves as well as unconventional superconductivity with mixed singlet and triplet amplitudes.
