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…
Finite-Temperature Thermally-Assisted-Occupation Density Functional Theory, Ab Initio Molecular Dynamics, and Quantum Mechanics/Molecular Mechanics Methods
Shaozhi Li, Jeng-Da Chai
Recently, thermally-assisted-occupation density functional theory (TAO-DFT) [J.-D. Chai, J. Chem. Phys. 136, 154104 (2012)] has been demonstrated to be an efficient and accurate el…
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…
