Magnetic Ordering in Moiré Graphene Multilayers from a Continuum Hartree+U Approach
Christopher T. S. Cheung, Valerio Vitale, Lennart Klebl +5
Recently, symmetry-broken ground states, such as correlated insulating states, magnetic order and superconductivity, have been discovered in twisted bilayer graphene (tBLG) and twi…
Short vs. long range exchange interactions in twisted bilayer graphene
Alejandro Jimeno-Pozo, Zachary A. H. Goodwin, Pierre A. Pantaleón +6
We discuss the effect of long-range interactions within the self-consistent Hartree-Fock (HF) approximation in comparison to short-range atomic Hubbard interactions on the band str…
The interplay of field-tunable strongly correlated states in a multi-orbital moiré system
Aidan J. Campbell, Valerio Vitale, Mauro Brotons-Gisbert +5
The interplay of charge, spin, lattice, and orbital degrees of freedom leads to a wide range of emergent phenomena in strongly correlated systems. In heterobilayer transition metal…
Exciton-polarons in the presence of strongly correlated electronic states in a MoSe/WSe moiré superlattice
Aidan J. Campbell, Mauro Brotons-Gisbert, Hyeonjun Baek +5
Two-dimensional moiré materials provide a highly tunable platform to investigate strongly correlated electronic states. Such emergent many-body phenomena can be optically probed in…
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…
