Low temperature high-frequency monolayer graphene conductivity as a manifestation of Zitterbewegung

We consider the Zitterbewegung of Dirac electrons in the monolayer graphene as the nonrelativistic analog of the phenomenon predicted by E. Schrödinger for the relativistic electrons in the free space. So we show that the Dirac electrons of monolayer graphene oscillate, i.e. produce fast fluctuation of an electron position around the mean value with rather high frequency but much less than the relativistic electrons in the free space. We also study relation between the Zitterbewegung of the conductivity electrons wave packet formed by the Fermi-Dirac distribution and the high-frequency complex conductivity of the monolayer graphene. Thus we find that the electromagnetic resonance properties of the monolayer graphene can be simulated by the set of the equivalent oscillatory circuits. This is useful in order to impart illustrativeness to electromagnetic processes that is particularly important for incorporation of graphene into electronic systems.
