1	Exact Diagonalization of Few-electron Quantum Dots Hakimi, Shirin January 2009 (has links) <p>We consider a system of few electrons trapped in a two-dimensional circularquantum dot with harmonic confinement and in the presence of ahomogeneous magnetic field, with focus on the role of e-e interaction. Byperforming the exact diagonalization of the Hamiltonian in second quantization,the low-lying energy levels for spin polarized system are obtained. The singlet-triplet oscillation in the ground state of the two-electron system showing up inthe result is explained due to the role of Coulomb interaction. The splitting ofthe lowest Landau level is another effect of the e-e interaction, which is alsoobserved in the results.</p> two-dimensional quantum dot strongly correlated system few-electron system exact diagonalization Lanczos method Landau level fractional quantum Hall effect Wigner crystal Hartree-Fock approximation Second quantization Condensed matter physics Kondenserade materiens fysik
