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…
Polygonization of carbon nanotubes
Dmitry Golovaty, Shannon Talbott
We use a multiscale procedure to derive a simple continuum model of multiwalled carbon nanotubes that takes into account both strong covalent bonds within graphene layers and weak…
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…
A model of weak viscoelastic nematodynamics
Arkady I. Leonov
The paper develops a continuum theory of weak viscoelastic nematodynamics of Maxwell type. It may describe the molecular elasticity effects in mono-domain flows of liquid crystalli…
A Monte Carlo Simulation Study of the Mechanical and Conformational Properties of Networks of Helical Polymers. I General Concepts
Gustavo A. Carri, Richard Batman, Vikas Varshney +1
We study the mechanical and conformational properties of networks of helical polymers with a combination of Monte Carlo simulations based on the Wang-Landau algorithm and the Three…
