Driven square lattice of quantum dots in a magnetic field coupled to a cylindrical FIR-photon cavity
Vidar Gudmundsson, Vram Mughnetsyan, Hsi-Sheng Goan +6
We present a comprehensive computational study of driven quantum dot arrays in a square lattice configuration, subject to an external magnetic field and coupled to a cylindrical fa…
Signatures of broken symmetries in the excitations of a periodic 2DEG coupled to a cylindrical photon cavity
Vidar Gudmundsson, Vram Mughnetsyan, Hsi-Sheng Goan +6
In a two-dimensional electron gas (2DEG) in a periodic lateral superlattice subjected to an external homogeneous magnetic field and in a cylindrical far-infrared photon cavity we s…
Spin-phase transition in an array of quantum rings controlled by cavity photons
Vidar Gudmundsson, Vram Mughnetsyan, Hsi-Sheng Goan +5
We model a spin-phase transition in a two-dimensional square array, or a lateral superlattice, of quantum rings in an external perpendicular homogeneous magnetic field. The electro…
The tuning of para- and diamagnetic cavity photon excitations in a square array of quantum dots in a magnetic field
Vidar Gudmundsson, Vram Mughnetsyan, Hsi-Sheng Goan +5
We employ a ``real-time'' excitation scheme to calculate the excitation spectra of a two-dimensional electron system in a square array of quantum dots placed in a circular cylindri…
Magneto-optical properties of a quantum dot array interacting with a far-infrared photon mode of a cylindrical cavity
Vidar Gudmundsson, Vram Mughnetsyan, Hsi-Sheng Goan +5
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…
Magnetic properties of a cavity-embedded square lattice of quantum dots or antidots
Vram Mughnetsyan, Vidar Gudmundsson, Nzar Rauf Abdullah +3
We apply quantum electrodynamical density functional theory to obtain the electronic density, the spin polarization, as well as the orbital and the spin magnetization of square per…
