On the Properties and Cosmology of Q-balls
(Annales Universitatis Turkuensis AI 272, 2001)
The properties and cosmological importance of a class of non-topological solitons, Q-balls, are studied. Aspects of Q-ball solutions and Q-ball cosmology discussed in the literature are reviewed. Q-balls are particularly ...
Imprecise measurements in quantum mechanics
(Annales Universitatis Turkuensis AI 344, 2006-01-14)
In this thesis the structure and properties of imprecise quantum measurements are investigated. The starting point for this investigation is the representation of a quantum observable as a normalized positive operator ...
On Topological Solitons in The Faddeev-Skyrme Model and its Extensions
(Annales Universitatis Turkuensis AI 399, 2009-06-26)
The topological solitons of two classical field theories, the Faddeev-Skyrme model and the Ginzburg-Landau model are studied numerically and analytically in this work. The aim is to gain information on the existence and ...
