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…
Spin Symmetry in Thermally-Assisted-Occupation Density Functional Theory
Yu-Yang Wang, Jeng-Da Chai
For electronic systems with multi-reference (MR) character, Kohn-Sham density functional theory (KS-DFT) with the conventional exchange-correlation (xc) energy functionals can lead…
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…
