Twisted two-dimensional van der Waals materials are novel artificial systems exhibiting exotic electronic properties. These materials opened up new opportunities to tailor the electronic band structure and alter the intrinsic characteristics of the base materials. The formation of a Moiré pattern, due to slight lattice mismatches between two layers rotated by a small angle, results in a large super lattice and the inter-layer interaction lead to the hybridization of the band structure within this superlattice, consequently resulting in the emergence of flat electronic bands. The dominance of electron-electron interaction over the quenched kinetic motion of electrons in the flat bands facilitates collective behaviors of electrons and exhibits exotic quantum phenomena, such as unconventional superconductivity, correlated insulators, and topological magnets. Our research explores new twisted systems based on various van der Waals materials to discover new quantum phenomena and understand the microscopic mechanisms of these systems. Our lab is also focused on fabricating and developing devices from twisted materials for next-generation computational applications.
