Pseudogap in the lightly hole-doped triangular-lattice moiré Hubbard model
V. I. Kuz'min, M. A. Visotin, S. G. Ovchinnikov
The electronic structure of the lightly hole-doped triangular-lattice moiré Hubbard model is studied within cluster perturbation theory (CPT) using 13-site clusters for a fixed do…
