Magneto-optical properties of a quantum dot array interacting with a far-infrared photon mode of a cylindrical cavity

|
By Vidar Gudmundsson, Vram Mughnetsyan, Hsi-Sheng Goan, Jeng-Da Chai
| Physical Review B
We model the equilibrium properties of a two-dimensional electron gas in a square lateral superlattice of quantum dots in a GaAs heterostructure subject to an external homogeneous perpendicular magnetic field and a far-infrared circular cylindrical photon cavity with one quantized mode, the TE011 mode.

Controlling the excitation spectrum of a quantum dot array with a photon cavity

|
By Vidar Gudmundsson, Nzar Rauf Abdullah, Kurdistan Region, Vram Mughnetsyan
| Physical Review B
We use a recently proposed quantum electrodynamical density theory functional in a real-time excitation calculation for a two-dimensional electron gas in a square array of quantum dots in an external constant perpendicular magnetic field to model the influence of cavity photons on the excitation spectra of the system. The excitation is generated by a short electrical pulse.
