Tunable quantum criticalities in an isospin extended Hubbard model simulator

Qiao Li et al.

Summary: Studying strong electron correlations is essential for advancing condensed matter physics. Recent research has demonstrated that moire heterostructures of van der Waals materials can serve as highly tunable quantum platforms for studying strongly correlated quantum physics. In this study, tunable quantum criticalities are observed in a simulator of the extended Hubbard model with spin-valley isospins in chiral-stacked twisted double bilayer graphene. The results showcase the potential of using this solid-state simulator to explore exotic quantum critical states and behaviors.
