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…
Magneto-optical properties of electron gas in a chain of planar quantum rings: Effect of screening on the signature of quantum phase interference
Armen Harutyunyan, Vram Mughnetsyan, Albert Kirakosyan +1
The equilibrium properties and interminiband transitions for Hartree-interacting two-dimensional electron gas in a one-dimensional chain of planar quantum rings subjected to a tran…
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…
