Abstract:
This dissertation investigates properties of two-dimensional many-body
systems. Studies are performed using the Spin-Density Functional
Theory with the Local Spin-Density Approximation, and numerical exact
diagonalization. The properties studied include symmetry-breaking
states in few-electron quantum dots, gaps in confined few-body
systems, magnetic properties of cold fermionic atoms in optical
lattices, and vortex formation in few-body systems. The dissertation
also studies the properties of the SDFT-LSDA method for many-body
calculations itself.
There will be some refreshments served in the Matfys lunch room before the disputation at 9:30.
