Critical Behavior in Graphene with Coulomb Interactions
Jianhui Wang, H. A. Fertig, Ganpathy Murthy
We demonstrate that in the presence of Coulomb interactions, electrons in graphene behave like a critical system, supporting power law correlations with interaction-dependent expon…
Effective Time Reversal Symmetry Breaking and Energy Spectra of Graphene Armchair Rings
Tianhuan Luo, A. P. Iyengar, H. A. Fertig +1
We study the energy spectra and wavefunctions of graphene rings formed from metallic armchair ribbons, near zero energy, to search for properties which may be identified with "effe…
Linear Response and the Thomas-Fermi Approximation in Undoped Graphene
L. Brey, H. A. Fertig
We analyze the range of validity of Thomas Fermi theory for describing charge density modulations induced by external potentials in neutral graphene. We compare exact results obtai…
Majorana fermions of a two-dimensional Px+iPy superconductor
Yaacov E. Kraus, Assa Auerbach, H. A. Fertig +1
To investigate Majorana fermionic excitations of a superconductor, the Bogoliubov-de-Gennes equation is solved on a sphere for two cases: (i) a vortex-antivortex pair at…
