Hidden antiferromagnetism, persistent valley fluctuations, and crossovers in triangular-lattice M-point moiré materials via determinantal quantum Monte Carlo
Konstantinos Vasiliou, Dumitru CÄlugÄru, 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. Co…
Mixed-dimensional quantum Monte Carlo studies of M-point moiré materials
Dumitru CÄlugÄru, 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 B…
Engineering topological flat bands in -valley moiré systems with Ising-type SOC: twisted 1T-ZrS and 1T-SnSe
Hanqi Pi, Yves H. Kwan, Haoyu Hu +8
Twisted moiré superlattices hosting topological flat bands provide a platform to explore the interplay between topology and correlations. Here we investigate topological band stru…
Twisted Bilayer Graphene Lifetimes At Integer Fillings: An Analytic Result
Haoyu Hu, Yuelin Shao, Lorenzo Crippa +5
Twisted bilayer graphene near integer fillings hosts correlated single-particle excitations whose dispersion and linewidth are increasingly accessible experimentally. We study thes…
Interplay between many-body correlations, strain and lattice relaxation in twisted bilayer graphene
Lorenzo Crippa, Gautam Rai, Dumitru CÄlugÄru +6
In twisted bilayer graphene, a unified understanding of the mechanisms governing temperature-dependent electronic spectra and thermodynamic properties remains controversial despite…
Obtaining the Spectral Function of Moiré Graphene Heavy-Fermions Using Iterative Perturbation Theory
Dumitru CÄlugÄru, Haoyu Hu, Lorenzo Crippa +6
The spectral functions of twisted bilayer graphene (TBG) in the absence of strain have recently been investigated in both the symmetric and symmetry-broken phases using dynamical m…
