Designer magnetoplasmonics for adaptive nano-optics
(2017-08-24)
Materials that provide real-time control of the fundamental properties of light at visible and near-infrared frequencies enable the essential components for future optical devices. Metal nanostructures that couple ...
Excited States in Negative Ions
(2014-05-07)
This thesis covers experimental studies of atomic negative ions with the main goal of increasing our fundamental understanding of these fragile quantum systems. Comparisons of measurements and calculations have been used ...
Magnetodynamics of pseudo spin valves investigated using co-planar waveguide and spin torque ferromagnetic resonance techniques
(2017-05-17)
Nanocontact spin-torque nano-oscillators (NC-STNOs), based on magnetic multilayers, can generate a wide range of highly nonlinear localized and propagating spin wave modes for use in magnonics. In this thesis, we study ...
Electromechanical Phenomena in Superconducting and Normal Nanostructures
(2013-05-08)
This thesis summarizes a series of theoretical studies on the electromechanical properties of nanostructures made of superconducting and/or metallic elements. The first part of the work is devoted to the analysis of the ...
On the Control of Nematic Liquid Crystal Alignment
(2013-05-07)
Liquid crystal displays (LCDs) are incorporated in a great variety of electronic devices such as laptops, mobile phones, TV sets, etc. The performance of LCDs depends strongly on the alignment of liquid crystal and therefore ...
Towards a relativistically covariant many-body perturbation theory - With numerical implementation to helium-like ions
(2010-03-30)
The experimental results for simple atomic systems have become more and more accurate and in order to keep up with the experimental achievements the theoretical procedures have to be refined. Recent accurate experimental ...
Angular dynamics of small particles in fluids
(2015-11-20)
This thesis concerns the angular motion of small particles suspended in fluid flows. A small particle experiences a hydrodynamic torque due to the local fluid velocity, and this torque leads to rotational motion. When ...
Multi-photon microscopy enhanced: Exploring annular beams and gold nano-particles for improved imaging
(2016-05-09)
Laser scanning multiphoton microscopy (MPM) has emerged as a powerful tool for non-invasive three-dimensional imaging of biological tissue. The localized focal region enables confocality without the use of a physical pinhole ...
Ionization of large molecules with short laser pulses
(2010-03-24)
The decay dynamics of fullerenes and polyaromatic hydrocarbons (PAH)
after femtosecond-laser excitation have been studied experimentally by electron
momentum mapping and mass spectrometry. The electron spectra of
fullerenes ...
Non-linear Optical Microscopy and Spectroscopy for Biomedical Studies
(2012-11-21)
This thesis is based on the application of non-linear optical microscopy and spectroscopy
techniques within biomedical research. Non-linear optical microscopy
gives the possibility of exciting fluorophores using near ...
