• graphene-based quantum dot system provides a platform for potential applications of nanoelectronics. Furthermore, we also propose an experimental setup for performing measurements in order to verify our model. Keywords: graphene; Kondo effect; magnetic field; pseudogap Anderson model; quantum dot

• ][39][40]. The choice of electrodes can have a significant effect on the transport properties of the QD system. In the present work, we study the nonequilibrium Kondo effect and the transport properties in a QD coupled to graphene-based leads by solving the pseudogap Anderson model [36][37][38][39][40

• impurity have been explored via density functional calculations [63][64]. In several studies, the Kondo effect in graphene is treated within the framework of magnetic impurities with massless Dirac fermions via a pseudogap Anderson model [41][42][43][44][45][65][66]. Dell’Anna showed that in graphene
