Kekulé spirals and charge transfer cascades in twisted symmetric trilayer graphene
Ziwei Wang, Yves H. Kwan, Glenn Wagner +3
We study the phase diagram of magic-angle twisted symmetric trilayer graphene in the presence of uniaxial heterostrain and interlayer displacement field. For experimentally reasona…
Itinerant magnetism in the triangular lattice Hubbard model at half-doping: Application to twisted transition-metal dichalcogenides
Yuchi He, Roman Rausch, Matthias Peschke +4
We use unrestricted Hartree-Fock, density matrix renormalization group, and variational projected entangled pair state calculations to investigate the ground state phase diagram of…
Coulomb-driven band unflattening suppresses -phonon pairing in moiré graphene
Glenn Wagner, Yves H. Kwan, Nick Bultinck +2
It is a matter of current debate whether the gate-tunable superconductivity in twisted bilayer graphene is phonon-mediated or arises from electron-electron interactions. The recent…
Electrons interacting with Goldstone modes and the rotating frame
Konstantinos Vasiliou, Yuchi He, Nick Bultinck
We consider electronic systems with a spontaneously broken continuous symmetry. The scattering vertex between electrons and Goldstone modes is calculated over the entire Brillouin…
Finite-Entanglement Scaling of 2D Metals
Quinten Mortier, Ming-Hao Li, Jutho Haegeman +1
We extend the study of finite-entanglement scaling from one-dimensional gapless models to two-dimensional systems with a Fermi surface. In particular, we show that the entanglement…
Electron-phonon coupling and competing Kekulé orders in twisted bilayer graphene
Yves H. Kwan, Glenn Wagner, Nick Bultinck +3
Recent scanning tunneling microscopy experiments [K.P. Nuckolls et al., arXiv:2303.00024] have revealed the ubiquity of Kekulé charge-density wave order in magic-angle twisted bila…
Superconductivity from repulsive interactions in Bernal-stacked bilayer graphene
Glenn Wagner, Yves H. Kwan, Nick Bultinck +2
A striking series of experiments have observed superconductivity in Bernal-stacked bilayer graphene (BBG) when the energy bands are flattened by applying an electrical displacement…
