Atomistic hartree theory and crystal field of twisted double bilayer graphene near the magic angle
Christopher T. S. Cheung, Zachary A. H. Goodwin, Valerio Vitale +2
Twisted double bilayer graphene (tDBLG) is a moiré material that has recently generated significant interest because of the observation of correlated phases near the magic angle. W…
Flat bands, electron interactions and magnetic order in magic-angle mono-trilayer graphene
Zachary A. H. Goodwin, Lennart Klebl, Valerio Vitale +6
Starting with twisted bilayer graphene, graphene-based moiré materials have recently been established as a new platform for studying strong electron correlations. In this paper, we…
Flat band properties of twisted transition metal dichalcogenide homo- and heterobilayers of MoS, MoSe, WS and WSe
Valerio Vitale, Kemal Atalar, Arash A. Mostofi +1
Twisted bilayers of two-dimensional materials, such as twisted bilayer graphene, often feature flat electronic bands that enable the observation of electron correlation effects. In…
Optical read-out of Coulomb staircases in a moiré superlattice via trapped interlayer trions
Hyeonjun Baek, Mauro Brotons-Gisbert, Aidan Campbell +5
Moiré patterns with a superlattice potential can be formed by vertically stacking two layered materials with a relative twist or lattice constant mismatch. The moiré superlattice c…
