Density of states of disordered graphene
Ben Yu-Kuang Hu, E. H. Hwang, S. Das Sarma
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-consist…
Electron-Electron Interactions in Graphene
S. Das Sarma, Ben Yu-Kuang Hu, E. H. Hwang +1
We discuss the validity (or not) of the ring-diagram approximation (i.e. RPA) in the calculation of graphene self-energy in the weak-coupling () limit, showing that RPA…
Many-body exchange-correlation effects in graphene
E. H. Hwang, Ben Yu-Kuang Hu, S. Das Sarma
We calculate, within the leading-order dynamical-screening approximation, the electron self-energy and spectral function at zero temperature for extrinsic (or gated/doped) graphene…
Density dependent exchange contribution to in extrinsic graphene
E. H. Hwang, Ben Yu-Kuang Hu, S. Das Sarma
We calculate in extrinsic graphene as a function of carrier density at zero temperature by obtaining the electronic self-energy within the Hartree-Fock a…
Relativistic momentum and kinetic energy, and
Ben Yu-Kuang Hu
Based on relativistic velocity addition and the conservation of momentum and energy, I present derivations of the expressions for the relativistic momentum and kinetic energy, and…
Relativistic addition of perpendicular velocity components from the constancy of the speed of light
Ben Yu-Kuang Hu
Mermin [Am. J. Phys. {\bf 51}, 1130--1131 (1983)] derived the relativistic addition of the parallel components of velocity using the constancy of the speed of light. In this note,…
