Density of states of disordered graphene
We calculate the average single-particle density of states in graphene with disorder due to impurity potentials. For unscreened short-ranged impurities, we use the non-self-consistent and self-consistent Born and T-matrix approximations to obtain the self-energy. Among these, only the self-consistent T-matrix approximation gives a nonzero density of states at the Dirac point. The density of sta...

متن کاملElectronic states in topologically disordered systems
Networks generated from Voronoi tessellations of space are prototypes for topo-logically disordered systems. In order to assess the effects of random coordination on the statistical properties of energy spectra, we analyze tight-binding models for planar topolog-ically disordered systems. To this end, the networks are generated by a simple topological model covering a wide range of naturally ob...
متن کاملError analysis of free probability approximations to the density of states of disordered systems.
Theoretical studies of localization, anomalous diffusion and ergodicity breaking require solving the electronic structure of disordered systems. We use free probability to approximate the ensemble-averaged density of states without exact diagonalization. We present an error analysis that quantifies the accuracy using a generalized moment expansion, allowing us to distinguish between different a...
متن کاملHigh-frequency vibrational density of states of a disordered solid.
We investigate the high-frequency behavior of the density of vibrational states in three-dimensional elasticity theory with spatially fluctuating elastic moduli. At frequencies well above the mobility edge, instanton solutions yield an exponentially decaying density of states. The instanton solutions describe excitations, which become localized due to the disorder-induced fluctuations, which lo...
