Moment Operators of Observables in Quantum Mechanics, with Applications to Quantization and Homodyne Detection
(Turun yliopistoAnnales Universitatis Turkuensis AI 380, 2008-01-19)
The questions studied in this thesis are centered around the moment operators of a quantum observable, the latter being represented by a normalized positive operator measure. The moment operators of an observable are ...
Cantilever enhanced photoacoustic spectroscopy: The First two decades
(Turun yliopisto, 2024-02-29)
Two decades ago, the first experiments with a novel optical microphone using a small silicon cantilever as its sensing element were conducted at the University of Turku. In retrospect, those experiments revealed the potential ...
Solar Twins and Solar Analogues in Galactic Surveys.
(Turun yliopistoAnnales Universitatis Turkuensis A I 497, 2014-11-22)
The Sun is a crucial benchmark for how we see the universe. Especially when it comes to the visible range of the spectrum, stars are commonly compared to the Sun, as it is the most thoroughly studied star.
In this work ...
On the Properties and Cosmology of Q-balls
(Turun yliopistoAnnales 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 ...
Two-dimensional atom localization and Raman cooling of tripod-type atoms
(Turun yliopistoAnnales Universitatis Turkuensis A I 471, 2013-09-20)
Both atom localization and Raman cooling, considered in the thesis, reflect
recent progress in the area of all-optical methods. We focus on twodimensional
(2D) case, using a four-level tripod-type atomic scheme for
atom ...
Non-Markovianity and Quantum Correlations in Qubit-Systems
(Turun yliopistoAnnales Universitatis Turkuensis A I 413, 2010-11-13)
In this Thesis I discuss the exact dynamics of simple non-Markovian systems. I focus on fundamental questions at the core of non-Markovian theory and investigate the dynamics of quantum correlations under non-Markovian ...
Characterization of Porous Silicon Nanoparticles for Biomedical Applications
(Turun yliopistoAnnales Universitatis Turkuensis A I 557, 2017-05-13)
Porous silicon (PSi) is an intriguing material for biomedical applications because a great variation of properties can be created by adjusting fabrication parameters.Physicochemical properties, including pore size, surface ...
On the effect of molecular structure and composition on the photofragmentation of biomolecules
(Turun yliopistoAnnales Universitatis Turkuensis A I 538, 2016-06-10)
The research on the interaction between radiation and biomolecules pro-vides valuable information for both radiobiology and molecular physics. While radiobiology is interested in the damage inflicted on the molecule upon ...
Long quasi-periodic oscillations of sunspots and small-scale magnetic structures
(Turun yliopisto, 2020-01-30)
This thesis presents the investigations and the interpretation of long quasi-periodic oscillations with periods more than 30 minutes observed in the magnetic field of sunspots, as well as, at millimeter radio emission ...
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 ...
