In this work we report results of ferromagnetic resonance studies of a 6% 15 nm (Ga,Mn)As layer, deposited on (001)-oriented GaAs. The measurements were performed with in-plane oriented magnetic field, in the temperature range between 5 K and 120 K. We observe a temperature induced reorientation of the effective in-plane easy axis from [(1) over bar 10] to [110] direction close to the Curie temper
Four high-spin collective bands have been populated in Er-154(68)86 via the Pd-110(Ti-48, (4)n gamma)Er-154 reaction. Average transition quadrupole moments Q(t) have been measured for three of the bands by using the Doppler-shift attenuation method. The strongest band has a value of Q(t) = 11.0 +/- 1.0 e b, similar to values found recently for four triaxial strongly deformed (TSD) bands in Er-157,
Spin relaxation theory and nuclear magnetic resonance spectroscopy in amphiphilic liquid crystals are presented. Group theory is used to determine the information content and the orientation dependence in spin relaxation experiments, and to investigate the combined effect of crystal and local symmetries and the effect of symmetry on multiple timescales. From lineshapes of a deuterated decanol and
The level structure of Er158 has been studied using the Gammasphere spectrometer via the Cd114(Ca48,4n) reaction at 215 MeV with both thin (self-supporting) and thick (backed) targets. The level scheme has been considerably extended with more than 200 new transitions and six new rotational structures, including two strongly coupled high-K bands. Configuration assignments for the new structures are
Automatic control of the plasma radial position, extracted from magnetic measurements, in EXTRAP-T2 is simulated. A simple model of plasma, surrounding copper shell and vertical field coils have been used. Design is concentrated on the PD type of controller with parameters studied in relation to power supply performance, i.e. switching frequency and maximum output voltage. Effects of saturation, n
The one-step conversion of unprotected sugars to sugar intermediates invented by the Shin-ichiro Shoda group at Tohoku University in Japan by using 2-chloro-1,3-dimethyl-imidazolinium chloride (DMC) as a dehydrative condensing agent is a relatively new way to synthesize carbohydrate derivatives. A great effort has been done to investigate the minimum requirement of bases, the suitable dehydrative
This work aims to make three-dimensional (3D) tomographic techniques more flexible and accessible to in-situ measurements in practical apparatus by allowing arbitrary camera placements that benefit applications with more restrictive optical access. A highly customizable, in-house developed tomographic method is presented, applying smoothness priors through Laplacian matrices and hull constraints b
Detecting and sorting spikes in extracellular neural recordings are common procedures in assessing the activity of individual neurons. In chronic recordings, passive electrode movements introduce changes in the shape of detected spike waveforms, and may thus lead to problems with identification and tracking of spikes recorded at separate instances in time, which is an important step in long-term m

This thesis examines the behavior of a single-qubit quantum system controlled by feedback. Key parameters such as coupling strength, dissipation, and detuning are explored to improve quantum coherence and stability. Based on the results, practical methods for controlling quantum systems are proposed to better understand quantum control techniques and then improve the performance and stability of q
Quantum communication has been widely used as an important component in many applications of quantum information science. It is naturally utilised in the fields of quantum optics and photonics. Quantum communication and quantum cryptography have been studied as a popular subject in research for many years. However, most of the quantum-communication devices are oversized and non-portable. This prob
In order to understand and manipulate biological function at the molecular level, access to high-resolution structures of biological macromolecules is essential, as structure is intimately linked to function. The two main experimental techniques that can achieve atomic, or near-atomic, resolution are crystallography and electron microscopy. Unfortunately, the experimental data alone is typically n
The interaction of extreme ultraviolet light with matter can lead to the emission of an electron in a process known as photoionization. The electron wavepacket (EWP) created in the continuum propagates on the ionic potential, resulting in a delay compared to an EWP propagating freely. The development of extreme ultraviolet attosecond light sources in recent years has opened the possibility to prob
