Beyond the Cosmological Principle
(Turun yliopistoAnnales Universitatis Turkuensis A I 545, 2016-09-14)
Simplifying the Einstein ﬁeld equation by assuming the cosmological principle yields a set of diﬀerential equations which governs the dynamics of the universe as described in the cosmological standard model. The cosmological ...
Evolution and Stellar Content of AGN Host Galaxies
(Turun yliopistoAnnales Universitatis Turkuensis A I 394, 2009-05-09)
In this dissertation, Active Galactic Nuclei (AGN) and their host galaxies are discussed. Together with transitional events, such as supernovae and gamma-ray bursts, AGN are the most energetic phenomena in the Universe. ...
Spinor Bose-Einstein Condensates and Topological Defects
(Turun yliopistoAnnales Universitatis Turkuensis AI 378, 2007-12-01)
This thesis concentrates on the topological defects of spin-1 and spin-2 Bose-Einstein condensates, the ground states of spin-3 condensates, and the inert states of spinor condensates with arbitrary spin. Our work is based ...
Stochastic descriptions and memory effects in open system dynamics
(Turun yliopistoAnnales Universitatis Turkuensis A I 504, 2015-01-10)
Atomic scale engineering and understanding of novel interfaces between oxide films and semiconductor crystals
(Turun yliopistoAnnales Universitatis Turkuensis A I 551, 2017-02-04)
Surface properties of semiconductor crystals play a significant role in the operation of different devices like transistors, LEDs, and solar cells. For better performance of the devices, it is ...
Circular Spectropolarimetric Studies of DQ White Dwarfs
(Turun yliopistoAnnales Universitatis Turkuensis A I 468, 2013-09-28)
This thesis summarizes studies of a class of white dwarfs (WDs) called DQ WDs. White dwarfs are the remnants of ordinary stars like our Sun that have run out of nuclear fuel. WDs are classified according to the composition ...

Memory effects and geometrical considerations in open quantum systems
(Turun yliopistoAnnales Universitatis Turkuensis A I 541, 2016-06-21)
This thesis discusses memory effects in open quantum systems with an emphasis on the Breuer, Laine, Piilo (BLP) measure of non-Markovianity. It is shown how the calculation of the measure can be simplifed and how quantum ...
