Controlling the excitation spectrum of a quantum dot array with a photon cavity
Vidar Gudmundsson, Vram Mughnetsyan, Nzar Rauf Abdullah +3
We use a recently proposed quantum electrodynamical density functional theory (QEDFT) functional in a real-time excitation calculation for a two-dimensional electron gas in a squar…
Single photon controlled steady state electron transport through a resonance DQD-Cavity system in a strong coupling regime
Halo Anwar Abdulkhalaq, Nzar Rauf Abdullah, Vidar Gudmundsson
We perform theoretical calculations to study steady-state electron transport in a double quantum dot, DQD, coupled to a quantized cavity photon field both in resonance and off-reso…
Photon and magnetic field controlled electron transport of a multiply-resonant photon-cavity double quantum dot system
Halo Anwar Abdulkhalaq, Nzar Rauf Abdullah, Vidar Gudmundsson
We study electron transport through double quantum dots (DQD) coupled to a cavity with a single photon mode. The DQD is connected to two electron reservoirs, and the total system i…
Thermal transport driven by Coulomb interactions in quantum dots: Enhancement of thermoelectric and heat currents
Bashdar Rahman Pirot, Nzar Rauf Abdullah, Ari Karim Ahmed
We investigate thermal transport in a serial asymmetric double quantum dot (DQD) coupled to two electron reservoirs with different temperatures. The inter- and intra-Coulomb intera…
Effects of coupling strength of the electron-photon and the photon-environment interactions on the electron transport through multiple-resonances of a double quantum dot system in a photon cavity
Halo Anwar Abdulkhalaq, Nzar Rauf Abdullah, Vidar Gudmundsson
We study electron transport properties through a double quantum dot (DQD) system coupled to a single mode photon cavity, DQD-cavity. The DQD system has a complex multilevel energy…
The effects of a far-infrared photon cavity field on the magnetization of a square quantum dot array
Vidar Gudmundsson, Vram Mughnetsyan, Nzar Rauf Abdullah +3
The orbital and spin magnetization of a cavity-embedded quantum dot array defined in a GaAs heterostructure are calculated within quantum-electrodynamical density-functional theory…
