Full configuration interaction approach to the few-electron problem in artificial atoms

0 Properties of few - electron artificial atoms

The spectra of quantum dots of different geometry (" quantum ring " , " quantum cylinder " , " spherical square-well " and " parabolic ") are studied. The stochastic variational method on correlated Gaussian basis functions and a large scale shell-model approach have been used to investigate these " artificial " atoms and their properties in magnetic field. Accurate numerical results are presen...

Benchmark Full Configuration Interaction Calculations for the Ground State of Three- Electron Harmonium Atoms

from linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar

chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...

The single electron transistor and artificial atoms

Modern techniques of lithography make it possible to confine electrons to sufficiently small dimensions that the quantization of both their charge and their energy are easily observable. When such confined electrons are allowed to tunnel to metallic leads a single electron transistor (SET) is created. This transistor turns on and off again every time one electron is added to the isolated region...

Rank-Restricted Full Configuration Interaction

which is a linear combination of n-electron configurations, or determinants, with coefficients equal to c!. The components |Φ! form an orthonormal basis of the wavefunction. The determinants are the set of features that comprise the wavefunction, so we can optimize them by minimizing the electronic energy. To determine the energy of the wavefunction c, the Schrödinger equation in matrix form reads
