Quasi-bound Electron Pairs in Two-Dimensional Materials with a Mexican-Hat Dispersion

We study quasi-bound states of two electrons that arise in two-dimensional materials with a Mexican-hat dispersion (MHD) at an energy above its central maximum. The width of the resonance of the local density of states created by pairs is determined by the hybridization of atomic orbitals, due to wh...
