Quantum pumping with adiabatically modulated barriers in graphene

. In this work, we focus on an adiabatic quantum pump device based on a graphene monolayer
modulated by two . In the vicinity of the point and in the presence of a potential , the low-energy
excitations of the gated graphene monolayer are described by the 2D Dirac
