New catalogs map the quantum possibilities of atomically thin materials
Twistronics has become a new alchemy of materials. By choosing atomically thin layers, stacking them and changing their relative angle, researchers can create electronic behavior absent from the original ingredients. Twisted graphene and transition metal dichalcogenides have already yielded superconductivity and fractional Chern insulators, states with fractionally charged excitations. One of…
This groundbreaking research maps the quantum possibilities of atomically thin materials, enabling the creation of entirely new forms of quantum matter. By twisting layers of materials, such as twisted graphene and transition metal dichalcogenides, researchers can alter their electronic behavior in ways not seen in their original states.
These new families of twisted materials present unique rules for electron movement and interaction, opening up novel quantum simulators and states. A recent study published in Science identifies over 1,600 candidates for twisting, with distinct electronic starting points that could lead to unprecedented quantum simulators. The first study extends topological quantum chemistry to nonmagnetic two-dimensional materials, while the second identifies promising candidate materials that could simulate various physical phenomena, including high-temperature superconductivity and one-dimensional electron chain behavior.
