Theory of Confined States of Positronium in Spherical and Circular Quantum Dots with Kane's Dispersion Law
K. G. Dvoyan, S. G. Matinyan, B. Vlahovic
Confined states of a positronium (Ps) in the spherical and circular quantum dots (QDs) are theoretically investigated in two size-quantization regimes: strong and weak. Two-band ap…
Electron tunneling in chaotic InAs/GaAs quantum ring
I. Filikhin, S. G. Matinyan, B. Vlahovic
Two dimensional InAs/GaAs quantum ring (QR) is considered using the effective potential approach. The symmetry of QR shape is violated as it is in the well-known Bohigas annular bi…
Quantum Mechanics of Semiconductor Quantum Dots and Rings
I. Filikhin, S. G. Matinyan, B. Vlahovic
We consider the several phenomena which are taking place in Quantum Dots (QD) and Quantum Rings (QR): The connection of the Quantum Chaos (QC) with the reflection symmetry of the Q…
Disappearance of Quantum Chaos in Coupled Chaotic Quantum Dots
Igor Filikhin, Sergei Matinyan, Branislav Vlahovic
Statistical properties of the single electron levels confined in the semiconductor (InAs/GaAs, Si/SiO2) double quantum dots (DQDs) are considered. We demonstrate that in the electr…
