Mass and radius constraints for neutron stars using X-ray timing, spectral, and polarization observations
(Turun yliopisto, 2020-12-11)
Neutron stars (NSs) are the most dense objects in the Universe that can be directly observed. The nature of the cold ultra-dense matter inside them is still unresolved, and determining the equation of state (EoS) of that ...
Controlling dynamics of open quantum systems
(Turun yliopisto, 2019-10-05)
Quantum mechanics has both deepened our understanding of the physical reality and allowed development of quantum technologies beating their classical counterparts in efficiency, security, and sensitivity. As a major downside, ...
Bl lac objects - view from the highest energies
(Turun yliopisto, 2020-06-16)
Relativistic jets launched by a super-massive black holes are among the most extreme particle accelerators in the Universe. BL Lac objects host a relativistic jet that points very close to our line of sight. They are the ...
Ab initio investigations of the durability of iron alloys and titanium
(Turun yliopisto, 2019-06-14)
In this ab initio work the oxidation of Fe-Cr, Fe-Al, Fe-Cr-V and Fe-Cr-Al, and the elasticity of Fe-Cr-Al alloys and titanium were investigated. The computational method used was Exact Muffin-tin Orbitals method (EMTO). ...
Developing Exchange-Correlation and Kinetic Energy Functional Approximations for Density Functional Theory
(Turun yliopisto, 2018-01-13)
A nearly endless amount of technology relies on the understanding of the properties of matter and materials. Because the properties emerge from the motion of the electrons within matter, deepest and most accurate understanding ...
Surface and bulk analysis of Sr2FeMoO6 thin films – Sr2FeMoO6 based spin valve
(Turun yliopisto, 2020-09-26)
This thesis deals with the analysis of Sr2FeMoO6 (hereafter refered to as SFMO) thin films. The material is a part of a versatile double perovskite structure family and exhibits potential attributes for basic scientific ...
Particle decay in the early universe
(Turun yliopisto, 2020-12-12)
Particle decay processes have deep and profound implications in cosmology and especially on various early universe particle processes. Common decay rates, which may be experimentally verifed e.g., in particle accelerators, ...
Super-critical accretion onto black holes and neutron stars
(Turun yliopisto, 2019-09-27)
Accretion is one of the most important processes in astrophysics. Accretion discs are observed in a very large wavelength range, from infrared to X-rays, and in a very large range of scales: from several kilometers (accretion ...
Exploring connections between open quantum systems, relativity and complex quantum networks
(Turun yliopisto, 2020-12-05)
This thesis is a collection of works focusing on interrelations between the fields of special relativity, open quantum systems and complex networks. As each of the aforementioned fields encompasses a huge variety of topics, ...
