Electrostatic Charge Fractionalization and Unconventional Superconductivity in Strained Monolayer Graphene
Two-dimensional systems with flat bands support correlated phases such as superconductivity and charge fractionalization. While twisted moire systems like twisted bilayer graphene have revealed such states, they remain complex to control. Here, we study monolayer graphene under uniaxial periodic strain, which forms a 1D moire and hosts two flat, sublattice-polarized bands. It is shown that this system exhibits features akin to its twisted counterparts, such as a pinning of the Fermi level to th…
