In this work, Sr2FeMoO6 (SFMO) thin films were studied with the main focus on their magnetic and magneto-transport properties. The fabrication process of pulsed laser deposited SFMO films was first optimized. Then the ...

Particle decay processes have deep and profound implications in cosmology and especially on various early universe particle processes. Common decay rates, which may be experimentally verifed e.g., in particle accelerators, ...

Realistic quantum systems interact with their environment and, as a consequence, may lose their quantum properties. This phenomenon is known as decoherence, and it keeps the many oddities of quantum mechanics at the level ...

The acceleration of solar energetic particles (SEPs) by flares and coronal mass ejections (CMEs) has been a major topic of research for the solar-terrestrial physics and geophysics communities for decades. This thesis ...

The aim of this thesis is to present a solution to the quantum phase problem of the single-mode optical field. The solution is based on the use of phase shift covariant normalized positive operator measures. These measures ...

In this thesis, we report on an experimental study of H, D and T atoms stabilized in solid molecular matrices of hydrogen isotopes at temperatures down to 70 mK. Previous experiments have been carried out at ...

In this Thesis various aspects of memory effects in the dynamics of open quantum systems are studied. We develop a general theoretical framework for open quantum systems beyond the Markov approximation which allows us to ...

This thesis contains dynamical analysis on four different scales: the Solar system, the Sun itself, the Solar neighbourhood, and the central region of the Milky Way galaxy. All of these topics have been handled through ...

Increasing demand of applications involving high-frequency devices such as wireless communications exposes limitations, problems, and different sources of signal loss. These issues continue to provide interesting and ...
