TL;DR: In this paper, the effects of transition metals (TM) on the electronic doping and scattering in graphene using molecular-beam epitaxy combined with in situ transport measurements were investigated, and it was shown that at high coverage, Pt films are able to produce doping that is either $n$ type or weakly $p$ type.

TL;DR: It is shown that the combination of unusual features specific to semimetals gives rise to a unique ordering and spacing of three characteristic energy scales, which not only is specific toSemimetals but which concomitantly provides a wide window for the observation of apparent field-induced metal-insulator behavior.

TL;DR: In this article, the authors present a gauge-invariant effective action for the Abelian-Higgs model (scalar electrodynamics) with a chemical potential on a ($1+1$)-dimensional lattice.

TL;DR: The Abelian Higgs model in 1+1 dimensions is shown to be a prime candidate for an experimental quantum simulation of a lattice gauge theory, and a discrete tensor reformulation is used to smoothly connect the space-time isotropic version used in most numerical lattice simulations to the continuous-time limit corresponding to the Hamiltonian formulation.

TL;DR: It is proposed that the dependence of the tunneling conductance on the distance between the tip and the adatom can provide a clear signature for the presence of local magnetic moments.
