Few-particle gas in strongly oblate asymmetric ellipsoidal quantum dot
The theoretical investigation of few-particle states in strongly oblate asymmetric ellipsoidal InAs quantum dot have been performed. It is shown, that in-plane confining potential can be described in the frame of two-dimensional asymmetric oscillator potential. Electron transitions in considered structure have been studied. Pair-interacting few-electron gas has been investigated by modeling the interaction potential between electrons in the frame of the Moshinsky interaction model. The character of long-wave optical transitions between the center of mass levels of the system has been obtained when Kohn’s theorem is realized.
期刊介绍：
Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section.
Theoretical as well as experimental papers are accepted.
