Constrained Random Phase Approximation of the effective Coulomb interaction in lattice models of twisted bilayer graphene
Tuomas I. Vanhala, Lode Pollet
Recent experiments on twisted bilayer graphene show the urgent need for establishing a low-energy lattice model for the system. We use the constrained random phase approximation to…

Magnetization, d-wave superconductivity and non-Fermi liquid behavior in a crossover from dispersive to flat bands
Pramod Kumar, Tuomas I. Vanhala, Päivi Törmä
We explore the effect of inhomogeneity on electronic properties of the two-dimensional Hubbard model on a square lattice using dynamical mean-field theory (DMFT). The inhomogeneity…
