Rhombohedral-stacked multilayer graphene hosts a pair of flat bands touching at zero
energy, which should give rise to correlated electron phenomena that can be tuned further …

Of the two stable forms of graphite, hexagonal and rhombohedral, the former is more
common and has been studied extensively. The latter is less stable, which has so far …

Flat-band systems with strongly correlated electrons can exhibit a variety of phenomena,
such as correlated insulating and topological states, unconventional superconductivity, and …

We derive an ab initio π-band tight-binding model for AB stacked bilayer graphene based on
maximally localized Wannier wave functions centered on the carbon sites, finding that both …

In crystalline solids, the interactions of charge and spin can result in a variety of emergent
quantum ground states, especially in partially filled, topological flat bands such as Landau …

ABC-stacked multilayer graphene (ABC-MLG) exhibits topological surface flat bands with a
divergent density of states, leading to many-body instabilities at charge neutrality. Here, we …

The crystallographic stacking order in multilayer graphene plays an important role in
determining its electronic properties. It has been predicted that a rhombohedral (ABC) …

At half filling, the very flat energy bands in rhombohedral-stacked tetralayer graphene are
unstable to electronic interactions, giving rise to electronic states with spontaneous broken …

We study interaction-mediated magnetism on the surface of ABC-multilayer graphene driven
by its zero-energy topological flat bands. Using the random-phase approximation, we treat …

We use a self-consistent Hartree-Fock approximation with realistic Coulomb interactions for
π-band electrons to explore the possibility of broken symmetry states in weakly disordered …
