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…
Rashba-Cavity Engineering of Energy Gaps and Spin-Hall Conductivity in Semiconducting Artificial Graphene
Maryam Mansouri, Vram Mughnetsyan, Armen Harutyunyan +2
We investigate the combined effect of a far - infrared cavity field and Rashba spin - orbit interaction on the band structure and transport properties of artificial graphene compos…
First-Principles Study of Structural, Electronic, Thermal, and Optical Properties of Quasi-2D C2 N2 O Using GGA and HSE06
Hemn. G. H, Nzar. R. Abdullah, Vidar Gudmundsson
DFT and AIMD are used to investigate the structural, stability, electronic, thermal, and optical properties of the quasi-2D C2N2O structure. The structure exhibits thermal and ener…
NIR and visible structured beam generation with a dual-force mechanical long-period fiber grating
Wen-Hsuan Kuan, Xin-Yu Hou, Kuei-Huei Lin +1
This work presents tunable generation of vortex, vector, and flat-top 1060-nm NIR beams in a few-mode fiber with a dual-force mechanical long-period fiber grating. By varying the a…
Enhanced Efficiency of Intermediate-Band Semiconductor Solar Cells Embedded with Quantum Dot Superlattices
Naira Petrosyan, Lilit Yeganyan, Aram Manaselyan +3
We present a multiscale approach for modeling an intermediate-band solar cell based on a GaAs-GaAlAs quantum dot superlattice of cubic symmetry. Our framework combines high-accurac…
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…
