Topological solitons, a class of stable nonlinear excitations, appear in diverse domains as in
the Skyrme model of nuclear forces. Here, we argue that similar excitations play an …

The single-particle and many-body properties of twisted bilayer graphene (TBG) can be
dramatically different from those of a single graphene layer, particularly when the two layers …

The polarizability of twisted bilayer graphene, due to the combined effect of electron–hole
pairs, plasmons, and acoustic phonons, is analyzed. The screened Coulomb interaction …

The recent discovery of superconductivity in magic-angle twisted bilayer graphene (TBLG)
has sparked a renewed interest in the strongly-correlated physics of sp 2 carbons, in stark …

Identifying the microscopic mechanism for superconductivity in magic-angle twisted bilayer
graphene (MATBG) is an outstanding open problem. While MATBG exhibits a rich phase …

van der Waals heterostructures of atomically thin layers with rotational misalignments, such
as twisted bilayer graphene, feature interesting structural moiré superlattices. Because of the …

Using an end-to-end differentiable implementation of the Kohn-Sham self-consistent field
equations, we obtain a highly accurate neural network–based exchange and correlation …

We propose an SU (4) spin-valley-fermion model to investigate the superconducting
instabilities of twisted bilayer graphene (TBG). In this approach, bosonic fluctuations …

We study the intervalley scattering induced by the Coulomb repulsion as a purely electronic
mechanism for the origin of superconductivity in a few layers of graphene. The pairing is …

The effects of the long range electrostatic interaction in twisted bilayer graphene are
described using the Hartree-Fock approximation. The results show a significant dependence …
