Magnetic properties of materials ranging from conventional ferromagnetic metals to strongly
correlated materials such as cuprates originate from Coulomb exchange interactions. The …

Many of the important phases observed in twisted transition metal dichalcogenide
homobilayers are driven by short-range interactions, which should be captured by a local …

Since the discovery of graphene, the development of two-dimensional material research has
enabled the exploration of a rich variety of exotic quantum phenomena that are not …

The valence flat bands in transition metal dichalcogenide (TMD) heterobilayers are shown to
exhibit strong intralayer spin-orbit coupling. I show that symmetry constrains the spin …

A series of recent experimental works on twisted MoTe 2 homobilayers have unveiled an
abundance of exotic states in this system. Valley-polarized quantum anomalous Hall states …

Understanding the Hubbard model is crucial for investigating various quantum many-body
states and its fermionic and bosonic versions have been largely realized separately …

The unusual structure and symmetry of low-energy states in twisted transition metal
dichalcogenides leads to large in-plane spin-exchange interactions between spin-valley …

We investigate strong coupling topological superconductivity in twisted moiré bilayer WSe 2.
Our approach is based on an effective tJ model with displacement-field-dependent complex …

The moiré Hubbard model describes correlations in certain homobilayer twisted transition
metal dichalcogenides. Using exact diagonalization and density matrix renormalization …

Evidence for correlated insulating and superconducting phases around regions of high
density of states was reported in the strongly spin-orbit coupled van der Waals material …
