Quantum complex networks
(Turun yliopisto, 2018-12-01)
This Thesis focuses on networks of interacting quantum harmonic oscillators and in particular, on them as environments for an open quantum system, their probing via the open system, their transport properties, and their ...
Quantum probes for complex systems
(2018-12-01)
Quantum probing is a fairly wide topic deepening its roots into many fields as it can borrow tools from, and be applied to, many-body physics, open quantum systems theory, quantum information and quantum thermodynamics. ...
Observations of energetic particles and radio emissions during multiple coronal mass ejections
(Turun yliopisto, 2018-08-08)
This doctoral thesis studies the characteristics of solar energetic particle (SEP) events and solar radio bursts during multiple coronal mass ejections (CMEs). As well the influences of solar and interplanetary (IP) processes ...
Activity and dust environment of comet 67P/Churyumov-Gerasimenko
(Turun yliopisto, 2018-06-01)
Comets are scientifically interesting objects for several reasons. Comets are among the most pristine objects of the Solar System, which can give us a way to directly study the imprints of the Solar System formation ...
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 ...
AlGaN-puolijohdepinnan ominaisuuksia
(Turun yliopisto, 2018-03-21)
Tässä Pro Gradu -tutkielmassa tutkittiin alumiinigalliumnitridi- (AlGaN) puolijohdepinnan ominaisuuksia. Päätavoitteena oli selvittää, miten kemiallinen vetykloridipohjainen (HCl) etsaus vaikuttaa AlGaN-pinnan kemiallisiin ...
Sähkökehrättyjen koaksiaalisten polymeerikuitujen valmistaminen ja
(Turun yliopisto, 2018-08-13)
Sähkökehräys on sähköstaattisia voimia hyödyntävä prosessi, jonka avulla voidaan valmistaa nanokokoluokan kuituja useista eri materiaaleista. Kapillaarissa oleva liuos induktiovarautuu voimakkaassa sähkökentässä ja kulkeutuu ...
Investigation and suppression of semiconductor–oxide related defect states : from surface science to device tests
(Turun yliopisto, 2019-02-22)
Many present challenges in semiconductor technology are related to utilizing solid structures with atomic scale dimensions and materials with higher charge carrier mobility and/or other readily controllable properties. ...
Late-time near-infrared evolution of the ejecta and the equatorial ring of Supernova 1987A
(Turun yliopisto, 2018-05-23)
Supernova 1987A, located 50 kpc away in the Large Magellanic Cloud, is the closest supernova (SN) observed in the time of modern astronomy. The circumstellar medium of SN 1987A is characterised by a system of three rings ...
Relaksaatioaikojen mittaus- ja analysointimenetelmien standardisointi laadunvarmistamiseen ja tieteellisiin tutkimuksiin
(Turun yliopisto, 2018-09-05)
Magneettikuvaus (magnetic resonance imaging, MRI) on yksi modernin lääketieteen suurista saavutuksista. Se on merkittävä kuvantamistekniikka, joka
tarjoaa kuvattavasta kohteesta erinomaisen pehmytkudoskontrastin ...
