| contents | 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 the van Hove singularity and unconventional superconductivity. We also found inhomogeneous charge density waves for rational fractional fillings of the unit cell |
