High-precision polarimetric, broad-band spectroscopic and temporal studies of black hole X-ray binaries
(Turun yliopisto, 2021-10-08)
Black holes are among the most unusual objects in the Universe. Powered through accretion, they are strong sources of radiation in a broad energy range, from radio to hard X-rays. Stellar-mass black holes manifest themselves ...
Spin-Dynamics in Cold Gases of 87Rb and Atomic Hydrogen. The spins they are a-changin’
(Turun yliopistoAnnales Universitatis Turkuensis A I 445, 2012-10-06)
In this thesis the dynamics of cold gaseous atoms is studied. Two different atomic species and two different experimental techniques have been used.
In the first part of the thesis experiments with Bose-Einstein condensates ...
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, ...
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 ...
Quantum communication tasks
(Turun yliopisto, 2023-02-04)
Quantum theory is one of the most important theories in modern physics, yet the physical principles underlying the theory are anything but clear. Nonclassical features, such as entanglement, are often attributed as the key ...
Statistical properties of solar energetic proton events
(Turun yliopisto, 2023-05-30)
The Sun is the source of several different kinds of high-energy particles that are most prominently released in sudden large eruptions, known as solar energetic particle events. These particles, which escape the Sun and ...
Determination of absorbed dose by radiophotoluminescence dosimetry and Monte Carlo simulations
(Turun yliopisto, 2023-04-21)
Radiation therapy (RT) utilizes the harmfulness of ionizing radiation for good, with the goal of destroying cancer cells without damaging too much healthy tissue. Dosimetry is always needed to achieve this goal. Dosimetry ...
Memristor devices based on low-bandwidth manganites
(Turun yliopisto, 2022-12-12)
This dissertation investigates the phenomenon of resistive switching (RS) in lowbandwidth mixed-valence perovskite manganite oxides. In particular, the compounds Pr0.6Ca0.4MnO3 and Gd1−xCaxMnO3 with x between 0 and 1 are ...
MRI-only radiotherapy treatment planning of the brain
(Turun yliopisto, 2023-03-03)
Advancements in imaging methods have made it possible to create synthetic computed tomography (sCT) images from magnetic resonance imaging (MRI) data. MRI-based methods enable computed tomography (CT) to be omitted from ...
A study of III-V/HfO2 interfaces and silicon structure optimization
(Turun yliopisto, 2023-01-27)
Computational materials physics is a field where we try to understand the phenomena related to materials all around us. However we can only model a small sections portion of these materials in our computations, quantum ...
