Modified Dirac Hamiltonian for Efficient Quantum Mechanical Simulations of Micron Sized Devices
K. M. Masum Habib, Redwan N. Sajjad, Avik W. Ghosh
Representing massless Dirac fermions on a spatial lattice poses a potential challenge known as the Fermion Doubling problem. Addition of a quadratic term to the Dirac Hamiltonian c…

Quantum transport at the Dirac point: Mapping out the minimum conductivity from pristine to disordered graphene
Redwan N. Sajjad, Frank Tseng, K. M. Masum Habib +1
The phase space for graphene's minimum conductivity is mapped out using Landauer theory modified for scattering using Fermi's Golden Rule, as well as the Non-Equil…
