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 …

We study theoretically the magic-angle twisted bilayer graphene with proximity-induced
Ising and Rashba spin-orbit couplings on the top layer. Topological flat bands (with three …

On flat bands of the magic-angle twisted bilayer graphene, exotic correlation physics
unfolds. Phonons, through mediating an effective electron-electron interaction, can play a …

Helical trilayer graphene (hTG) exhibits a supermoiré pattern with large domains centered
around stacking points ABA and BAB, where two well-separated low-energy bands appear …

Twisted bilayer graphene (TBG) has elements in common with two paradigmatic examples
of strongly correlated physics: quantum Hall physics and Hubbard physics. On one hand …

Using a combined Dynamical Mean Field Theory and Hartree (DMFT+ H) calculation we
study the transport and optical properties of the 8-band heavy fermion model for Twisted …

We report on the observation of negative electronic compressibility in twisted bilayer
graphene for Fermi energies close to insulating states. To observe this negative …

Graphene, renowned for its exceptional electronic and optical properties as a robust 2D
material, traditionally lacks electronic correlation effects. Proximity coupling offers a …

We derive a minimal low-energy model for Bernal bilayer graphene and related
rhombohedral graphene multilayers at low electronic densities by constructing Wannier …

Magic-angle twisted bilayer graphene (MATBG) presents a fascinating platform for
investigating the effects of electron interactions in topological flat bands. The Bistritzer …
