Physical Modeling of Graphene Nanoribbon Field Effect Transistor Using Non-Equilibrium Green Function Approach for Integrated Circuit Design
… equation and 1D Schrödinger equations within the non-equilibrium Green’s function (NEGF) formalism. The quantum transport model fully treats short channel-length electrostatic effects and the quantum tunneling effects, leading to the technology exploration of graphene nanoribbon field effect …

MAJORANA FERMION IN TOPOLOGICAL SUPERCONDUCTOR AND MOTT‐SUPERFLUID TRANSITION IN CIRCUIT‐QED SYSTEM
… couplings. In Chapter 3, we use Keldysh non-equilibrium Green function method to study the two-lead tunneling in the superconducting nanowire with Rashba and Dresselhaus spin-orbit couplings with/without Coulomb interaction and disorder, and discuss the impact on the transport property. …

Physics and applications of magnetic interactions in topological insulators
… Hamiltonian describing the heterostructure is non-Hermitian with broadening that can obscure the mass gap. We calculate the Hall conductivity of the non-Hermitian effective Hamiltonian and show that it is no longer quantized due to the finite lifetime of quasiparticle states. When the …

Engineering relativistic fermions in condensed matter systems
… particle is much less than the speed of light, non-relativistic classical mechanics faithfully describes the motion of the particle. Analogously, using wave-particle duality, the non-relativistic description of classical mechanics may be applied to describe the motion of a free electron governed …
