11. Relaxation and Resonance in Brownian Motion-Coupled Resonators
Sammanfattning : In physics, there exists a number of paradigm systems – exactly solvable models that can represent a wide variety of physical realizations. My research is concerned with two of these paradigm systems: the harmonic oscillator and Brownian motion. LÄS MER
12. Multidimensional MRI of Myocardial Dynamics : Acquisition, Reconstruction and Visualization
Sammanfattning : Methods for measuring deformation and motion of the human heart in-vivo are crucial in the assessment of cardiac function. Applications ranging from basic physiological research, through early detection of disease to follow-up studies, all rely on the quality of the measurements of heart dynamics. LÄS MER
13. On multilayered system dynamics and waves in anisotropic poroelastic media
Sammanfattning : The mechanical and acoustic anisotropy of media is a governing factor in the behaviour of multilayered systems including such media. The understanding of the mechanisms conditioning the dynamic behaviour of multilayered systems is of paramount importance. LÄS MER
14. Ultrafast spin dynamics and relaxation in metallic ferromagnets
Sammanfattning : We performed ultrafast demagnetization measurements on epitaxial hcp-cobalt thin film with the easy axis in the plane of the film by pumping the sample with 400 nm radiation and probing the magneto-optic effects in the longitudinal magneto optic Kerr effect geometry using 800 nm radiation. The in-plane magnetic anisotropy of the sample enabled us to measure the demagnetization dynamics along two different crystalline directions, namely along the easy axis and at 45 degrees between the easy and hard axes.

15. Molecular Order and Dynamics in Nanostructured Materials by Solid-State NMR
Sammanfattning : Organic-inorganic nanostructured composites are nowadays integrated in the field of material science and technology. They are used as advanced materials directly or as precursors to novel composites with potential applications in optics, mechanics, energy, catalysis and medicine. LÄS MER
