Papers
Plasmons in graphene nanoribbons
Farhad Karimi,Irena Knezevic +1 more
TL;DR: In this paper, the authors calculate the dielectric function and plasmonic response of armchair and zigzag nanoribbons using the self-consistent field approach within the Markovian master equation formalism (SCF-MMEF).
Dielectric function and plasmons in graphene: A self-consistent-field calculation within a Markovian master equation formalism
TL;DR: In this article, the authors present a technique for calculating the dielectric function of nanostructures with an arbitrary band dispersion and Bloch wave functions, which accurately captures interband electron-hole pair generation, as well as both interband and intraband electron scattering with phonons and impurities.
Nonlinear optical response in graphene nanoribbons: The critical role of electron scattering
TL;DR: In this article, the authors used a quantum-mechanical master equation with a detailed treatment of scattering and showed that electron scattering has a critical effect on the optical nonlinearity of graphene nanoribbons, which cannot be captured via the commonly used relaxation-time approximation.
Optical Modulation by Conducting Interfaces
Farhad Karimi,Sina Khorasani +1 more
TL;DR: In this paper, the authors analyzed the interaction of a propagating guided electromagnetic wave with a quantum well embedded in a dielectric slab waveguide and derived the eigenstates of electrons and holes and the transition dipole moments.

Partially coherent electron transport in terahertz quantum cascade lasers based on a Markovian master equation for the density matrix
TL;DR: In this paper, the authors derived a Markovian master equation for the single-electron density matrix, applicable to quantum cascade lasers (QCLs), and compared the results with both experiment and simulation via nonequilibrium Green's functions (NEGF).
