Abstract
This dissertation investigates correlations in finite Fermi
systems. The atomic nuclei is the mainly studied system but also other
systems, like superconducting metallic grains and cold Fermionic gases
are considered.
The dissertation comprises of five original papers.
Paper I and II investigates the autocorrelation function of the difference
between experimental and theoretical nuclear masses. This quantity is
found to agree with estimates of Periodic Orbit theory assuming
underlying chaotic dynamics.
In Paper III and IV a semiclassical theory for the BCS pairing gap is
developed. It is found to agree well with experimental data for
nuclei. It is also applied to other finite systems,
superconducting metallic grains and cold Fermionic gases.
Paper V considers an extension of the BCS theory called the Particle
Number Projection method. The pairing shell energy is calculated using
the Strutinsky method for a large number of nuclei across the nuclear
chart. It is found that the BCS and projection methods give very
similar results for the pairing shell energy.
