The ability to control the underlying lattice geometry of a system may enable transitions
between emergent quantum ground states. We report in situ gate switching between …

Many-body interactions between carriers lie at the heart of correlated physics. The ability to
tune such interactions would allow the possibility to access and control complex electronic …

Moiré patterns of transition metal dichalcogenide heterobilayers have proved to be an ideal
platform on which to host unusual correlated electronic phases, emerging magnetism and …

Atomically thin layers of two-dimensional materials can be assembled in vertical stacks that
are held together by relatively weak van der Waals forces, enabling coupling between …

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

Two-dimensional moiré materials are formed by overlaying two layered crystals with small
differences in orientation or/and lattice constant, where their direct coupling generates moiré …

Moiré superlattices can be used to engineer strongly correlated electronic states in two-
dimensional van der Waals heterostructures, as recently demonstrated in the correlated …

Two-dimensional materials and their heterostructures constitute a promising platform to
study correlated electronic states, as well as the many-body physics of excitons. Transport …

Overlaying two atomic layers with a slight lattice mismatch or at a small rotation angle
creates a moiré superlattice, which has properties that are markedly modified from (and at …

The Mott insulator is a central concept in strongly correlated physics and manifests when the
repulsive Coulomb interaction between electrons dominates over their kinetic energy …
