Mesoscopic fluctuations of the pairing gap

Åberg, Sven LU ; Uhrenholt, Henrik LU and Leboeuf, Patricio (2008) 2nd Workshop on Nuclei and Mesoscopic Physics, 2007 995. p.173-184
Abstract
A description of mesoscopic fluctuations of the pairing gap in finite-sized quantum systems based on periodic orbit theory is presented. The size of the fluctuations are found to depend on quite general properties. We distinguish between systems where corresponding classical motion is regular or chaotic, and describe in detail fluctuations of the BCS gap as a function of the size of the system. The theory is applied to different mesoscopic systems: atomic nuclei, metallic grains, and ultracold fermionic gases. We also present a detailed description of pairing gap variation with particle number for nuclei based on a deformed cavity potential.
