Some properties of the eigenstates in the many-electron problem
J. Szeftel, A. Khater
A general hamiltonian of electrons in finite concentration, interacting via any two-body coupling inside a crystal of arbitrary dimension, is considered. For simplicity and wit…

Discretized dynamics of exchange spin wave bulk and edge modes in honeycomb nanoribbons with armchair edge boundaries
Doried Ghader, Antoine Khater
We develop a field theory to study the dynamics of long wavelength exchange spin wave excitations on honeycomb nanoribbons characterized by armchair edge boundaries and the Néel an…

Theory for the electronic structure of incommensurate twisted bilayer graphene
D. Ghader, D. Szczȩśniak, A. Khater
The experimental control over the twist angle in twisted bilayer graphene has not been reported and its realistic structure is most likely incommensurate. In this paper, we develop…
