Molecular pairing in twisted bilayer graphene superconductivity
We propose a theory for how the weak phonon-mediated interaction (JA= 1–4 meV) wins
over the prohibitive Coulomb repulsion (U= 30–60 meV) and leads to a superconductor in …

MS Sánchez, J González, T Stauber - arxiv preprint arxiv:2501.09197, 2025 - arxiv.org
In this work, we derive effective theories for magic-angle twisted bilayer graphene (MATBG)
based on the mean-field normal state at charge neutrality of a tight-binding model, thereby …
