Visualizing quantum modes and designing electronic structure across scales, Part II

Moiré materials have driven a revolution in condensed matter physics through the realization of a large variety of exotic quantum phenomena, ranging from superconductivity and correlated insulators to fractionalized Chern insulators. At the core of this revolution is the unique opportunity to program and design spatially varying electronic textures at will with multiple moiré length scales. While moiré potentials are typically viewed as small perturbations to the bare electronic dispersion, here we explore structural variations that strongly reshape these potentials, leading to spatial confinement that goes beyond the perturbative regime. We use minimally twisted mono–bilayer graphene, featuring alternating 50–150 nm triangular domains of Bernal and rhombohedral trilayer graphene, as a model system. The second part of this talk extends the discussion in part I to include magnetic confinement and moiré potentials across multiple length scales.
