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 ...
Magnetic connectivity in SEP events
(2019-10-30)
The Solar energetic particle (SEP) events are the main source of the energetic particles we observe in space. They pose a threat on spacecraft electronics and humans in space and have effects that can be observed even ...
Quantum information protocols and thermodynamics with open quantum systems
(Turun yliopisto, 2020-12-15)
The theory of open quantum systems deals with the inevitable interaction between a quantum system of interest and its surrounding environment, the resulting non-unitary dynamics of the system and its decoherence. On the ...
Optimaaliset kovariantit diskreetit suureet kvanttimekaniikassa
(2019-07-03)
Kvanttimekaniikassa mittaustapahtuma on monimutkaisempi käsite kuin klassisessa fysiikassa, sillä tutkittavaan systeemiin tehtävät mittaukset täytyy mallintaa systeemin ja mittalaitteen välisenä vuorovaikutuksena. ...
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 ...
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 ...
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 ...
The effect of gold nanorod doping on the photoinduced properties of polymer-azobenzene complex
(Turun yliopisto, 2018-10-01)
Azobenzenes are a group of dyes that exhibit interesting photoresponsive properties. The photoresponsive properties have been a subject of study for some decades and have potential applications in numerous fields, such as ...
The Starving Ellipticals of Fossil Groups
(Turun yliopisto, 2018-09-05)
Fossil Groups (FGs) are unique galaxy systems with extensive X-ray halos and large magnitude gaps between members. It has been theorized that they are old and dynamically relaxed systems formed by multiple galaxy mergers. ...
Yleistetyn todennäköisyysteorian tomografia
(2019-10-08)
Kvanttifysiikassa on olemassa selittämättömiä ilmiöitä ja monia tutkimattomia aihepiirejä. Jotta kvanttiteknologinen läpimurto olisi mahdollinen, pitää ymmärtää kvanttimekaniikka syvällisesti aina matemaattisesta perustasta ...
