Hidden antiferromagnetism, persistent valley fluctuations, and crossovers in triangular-lattice M-point moiré materials via determinantal quantum Monte Carlo
Konstantinos Vasiliou, Dumitru Călugăru, Johannes S. Hofmann +1
A new moiré material platform was recently proposed based on twisting two-dimensional atomic monolayers whose low-energy states lie at the three M-points of the Brillouin Zone. Con…
Mixed-dimensional quantum Monte Carlo studies of M-point moiré materials
Dumitru Călugăru, Konstantinos Vasiliou, Haoyu Hu +3
A new moiré-material platform has recently been proposed based on twisting two-dimensional triangular-lattice monolayers whose low-energy states lie at the three M points of the Br…
Mean-field Modelling of Moiré Materials: A User's Guide with Selected Applications to Twisted Bilayer Graphene
Yves H. Kwan, Ziwei Wang, Glenn Wagner +3
We review the theoretical modelling of moiré materials, focusing on various aspects of magic-angle twisted bilayer graphene (MA-TBG) viewed through the lens of Hartree-Fock mean-fi…
Putting a new spin on the incommensurate Kekulé spiral: from spin-valley locking and collective modes to fermiology and implications for superconductivity
Ziwei Wang, Glenn Wagner, Yves H. Kwan +3
We revisit the global phase diagram of magic-angle twisted bilayer and [symmetric] trilayer graphene (MA-TBG/TSTG) in light of recent scanning tunneling microscopy (STM) measuremen…
Emergent Interacting Phases in the Strong Coupling Limit of Twisted M-Valley Moiré Systems: Application to SnSe
Ming-Rui Li, Dumitru Calugaru, Yi Jiang +10
We construct an interacting Wannier model for both AA-stacked and AB-stacked twisted SnSe2, revealing a rich landscape of correlated quantum phases. For the AA-stacked case, the sy…
Domain wall competition in the Chern insulating regime of twisted bilayer graphene
Yves H. Kwan, Glenn Wagner, Nilotpal Chakraborty +2
We consider magic-angle twisted bilayer graphene (TBG) at filling , where experiments have observed a robust quantized anomalous Hall effect. This has been attributed to the…
