Correlations in Finite Fermi Systems - Semiclassics and Shell Structure

Uhrenholt, Henrik LU (2008)
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... (More)

Paper I and II investigates the autocorrelation function of the difference

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. (Less)
