Graphene’s discovery marked a significant breakthrough in the field of materials science. Its exceptional properties and possible uses garnered significant interest. Utilizing chemical methods to control its electronic properties opened doors for creating a diverse range of graphene-based chemical derivatives. Electrons in graphene behaving like massless relativistic particles results in the observation of a number of very peculiar electronic properties - like Klein tunneling and the absence of localization. Quantum spin transport modeling and computer simulations for this novel material is still in its early stages of development. This study aims to develop the spin-isospin-pseudospin (SIPMQT) magnetization quantum transport of graphene and investigate similar materials with Dirac-like energy band structure. This is done by utilizing the tight-binding band structure calculation of graphene to determine the different spin degrees of freedom that govern its quantum transport properties. Applications to spintronics, pseudo-spintronics, and valleytronics are envisaged for graphene and other materials, such as, some Transition-metal-dichalcogenide monolayers, diamond, Bismuth, Silicon, Carbon nanotubes, Aluminium arsenide and silicene.
