Abstract
This project proposes a Quantum Phase Transition (QPT) in 3D Dirac-Weyl semimetals with adatoms. Particularly for the graphene monolayer hosting a pair of adatoms collinear with the center of a hexagonal cell, A.C. Seridonio et al have shown in Phys. Rev. B 92 045409 (2015) that the system pseudogap with cubic scaling on energy, namely $\Delta\propto|\varepsilon|^{3},$ gives rise to spin-…
