The rich phenomenology of twisted bilayer graphene (TBG) near the magic angle is believed to arise from electron correlations in topological flat bands. An unbiased approach to this problem is highly desirable, but also particularly challenging, given the multiple electron flavors, the topological obstruction to defining tight-binding models and the long-ranged Coulomb interactions. While numerical simulations of realistic models have thus far been confined to zero temperature, typically… 
Theory of Correlated Insulators and Superconductivity in Twisted Bilayer Graphene.
A model elucidates how the intricate form of the interactions and the particle-hole asymmetry of the electronic structure determine the phase diagram and explains how subtle differences between devices may lead to the different behaviors observed experimentally.
Detecting symmetry breaking in magic angle graphene using scanning tunneling microscopy

Nature of the Correlated Insulator States in Twisted Bilayer Graphene.
It is found that gaps between the flat conduction and valence bands open at neutrality over a wide range of twist angles, sometimes without breaking the system's valley projected C_{2}T symmetry.
Unconventional superconductivity in magic-angle graphene superlattices
The realization of intrinsic unconventional superconductivity is reported—which cannot be explained by weak electron–phonon interactions—in a two-dimensional superlattice created by stacking two sheets of graphene that are twisted relative to each other by a small angle.
Origin of Mott Insulating Behavior and Superconductivity in Twisted Bilayer Graphene
A remarkable recent experiment has observed Mott insulator and proximate superconductor phases in twisted bilayer graphene when electrons partly fill a nearly flat mini-band that arises a `magic'

It is shown that the modulation of the charge density significantly modifies the electronic structure, which can make an important contribution to superconductivity through electron-assisted hopping.
Valence Bond Orders at Charge Neutrality in a Possible Two-Orbital Extended Hubbard Model for Twisted Bilayer Graphene.
An extended Hubbard model on a honeycomb lattice with two orbitals per site at charge neutrality with unbiased large-scale quantum Monte Carlo simulations is investigated, finding the quantum critical point to belong to the 3D N=4 Gross-Neveu chiral XY universality with the critical exponents obtained at high precision.
