The concept of emergence is at the heart of the condensed matter:聽 Although all materials are composed of atoms and electrons, these particles can organize in various ways, giving rise to emergent phases and phenomena that can be dramatically rich and cannot be understood by studying the individual constituents. The emergent quantum phases, however, depend sensitively on the charge carrier density, symmetry, electron-electron interactions, and other material parameters. How we can precisely control those parameters to realize new quantum emergence becomes a great challenge.

Two-dimensional vdW materials provide an extremely powerful material platform to design and study emergence. Specifically, their chemical potential can be controlled by electrostatic gating. Their symmetry and electronic structures can be designed by layer stacking. They can be coupled with superconductors/ferromagnets for proximity effects. They can be integrated into cavity/plasmonic structures for enhanced light-matter interaction. Particularly, they can form moir茅 superlattices through interference between two mismatched atomic layers. 聽Moir茅 superlattices can host a series of emergent phases, including correlated insulators, superconductors, topological magnets, and ferroelectricity.
