dc.description.abstractOppgaven handler om en generalisert variasjonel Monte Carlo (VMC) løser brukt til å regne ut grunntilstander og en-legeme-tettheter til kvantesystemer. Systemene studert er atomene helium, beryllium og neon, molekyler for helium og beryllium og kvantedotter i to og tre dimensjoner. Metoden har blitt implementert med Metropolis algoritme og såkalt importance sampling for å forbedre nøyaktigheten. For atomer, i tillegg til slater-type orbitaler, er gauss-type orbitaler også implementert. Effekter i kvantedotter ved lavere frekvens i de harmoniske oscillator orbitalene er også studert, i to og tre dimensjoner.nob
dc.description.abstractIn this thesis a simple variational Monte Carlo (VMC) method is used to calculate ground state energies and one-body densities of several quantum systems: the atoms helium, beryllium, and neon, molecules dihydrogen and diberyllium, and quantum dots in two and three dimensions. The method has been implemented with the Metropolis algorithm and importance sampling to improve accuracy. For atoms, in addition to using slater type orbitals, Gaussian type orbitals has also been implemented. Furthermore effects in the quantum dots when the frequency in the harmonic oscillator orbitals is lowered has been studied in both two and three dimensions.eng
