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 ...
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 ...
Particle observations in near-earth space: Design and verification of particle instruments for CubeSat experiments
(Turun yliopisto, 2021-12-15)
This doctoral thesis presents the design, simulation, and calibration of two instruments developed to study energetic charged particles in low-Earth orbit. The near-Earth energetic charged particle populations include ...
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 ...
Electroencapsulation and electrospraying of pharmaceutical materials in preparation for oral drug delivery applications
(Turun yliopisto, 2019-02-09)
In bi-polar parallel nozzle electroencapsulation, two oppositely charged droplet jets are produced by electrospraying (electrostatic atomization), a method of extracting micro- or nanodroplets from a body of liquid using ...
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. ...
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. ...
Investigation of properties of solar energetic particles and geomagnetic storms related to coronal mass ejections
(Turun yliopisto, 2019-12-19)
Solar energetic particles (SEPs) and geomagnetic storms related to coronal mass ejections (CMEs) are a major research topic in solar-terrestrial and geospace physics. Solar energetic particles and coronal mass ejections ...
Electrostatic instrumentation and measurements on powders and powder mixtures
(Turun yliopisto, 2019-05-25)
In the powder industry, such as the pharmaceutical or chemical industry, powder particles collide frequently with the surrounding surfaces and with other particles and become electrostatically charged in different processes. ...
