We apply cluster dynamical mean field theory with an exact-diagonalization impurity solver to a Hubbard model for magic-angle twisted bilayer graphene, built on the tight-binding model proposed by Kang and Vafek~\cite{kang2018}. This model applies to the magic angle $1.30^\circ$. We find that triplet superconductivity with $p+ip$ symmetry is stabilized by CDMFT, contrary to other triplet or singlet order parameters. A minimum of the order parameter exists close to quarter-filling, as observed… Expand

Magnetism of magic-angle twisted bilayer graphene
We investigate magnetic instabilities in charge-neutral twisted bilayer graphene close to so-called “magic angles” using a combination of real-space Hartree-Fock and dynamical mean-field theories. InExpand
Quantifying the Charge Carrier Interaction in Metallic Twisted Bilayer Graphene Superlattices
The proposed generalized Bloch–Grüneisen equation is applicable to a wide range of disciplines, including superconductivity and geology, and found that TBGs have a smoothly varied p-value, which implies that different mechanisms of the charge carrier interaction in TBG superlattices smoothly transition from one mechanism to another depending on λ and n.

The word "symmetry" is used in mathematics quite differently from in ordinary speech. In everyday life one applies it mainly to two-sided, right-left symmetry; but not so in mathematics. Admittedly,Expand
Symmetry, Maximally Localized Wannier States, and a Low-Energy Model for Twisted Bilayer Graphene Narrow Bands
We build symmetry adapted maximally localized Wannier states, and construct the low energy tight binding model for the four narrow bands of the twisted bilayer graphene. We do so when the twist angleExpand

A diagnosis of explicit symmetry breaking in the tight-binding constructions for symmetry-protected topological systems
It has been well established that for symmetry protected topological systems, the non-trivial topology prevents a real space representation using exponentially localized Wannier wavefunctions (WFs)Expand
