Numerical simulation of the combined quantum-electromagnetic problem in nano-structured devices

Full-wave multiphysics techniques aimed at the investigation of the combined electromagnetic-coherent transport phenomena in carbon-based nano-structures/devices are presented. Advanced numerical tools, in the frequency (energy)-domain and time-domain and in multi-scale environment are derived. The quantum transport is modeled by discrete Hamiltonians at atomistic scale, Schrödinger equation, and/or Dirac/Dirac-like eqs. at continuous level. In the frequency-domain, a rigorous Poisson-coherent transport equation system is provided. In the time-domain, Maxwell equations are self-consistently coupled to the Schrödinger/Dirac equations.
