and byhopes that these elegantly tunable systems might be usefulelectronic materials. In this paper, we demonstrate an unan-ticipated low-energy property of graphene multilayers, whichfollows from an interplay between interlayer tunneling andthe chiral properties of low-energy quasiparticles in an iso-lated graphene sheet. Our conclusions apply in the strongestform to models with only nearest-neighbor interlayer tunnel-ing, but are valid over a broad ﬁeld range as we explainbelow. We ﬁnd that the low-energy band structure of anygraphene multilayer consists of a set of independent pseu-dospin doublets. Within each doublet, the bands are de-scribed by a pseudospin Hamiltonian of the form
