11. Constraining the top-Z coupling using the (ttWj)EW process with the ATLAS experiment : A search for physics beyond the Standard Model
Sammanfattning : The Standard Model (SM) of particle physics, having been confirmed by numerous experiments, is one of the most successful theories in physics. It describes all known elementary particles and their interactions through the electromagnetic, strong and weak force. LÄS MER
12. The growth of waves by wind as a problem in nonequilibrium statistical mechanics
Sammanfattning : In 1948, Casimir predicted a net attractive force between two perfectly conducting parallel plates due to electromagnetic vacuum fluctuations. By analogy, the interaction of two ships on a wavy sea has been named Maritime Casimir effect. This is an example of force generation in non-equilibrium systems. LÄS MER
13. Quantum mechanical effects on charge transport in two mesoscopic systems
Sammanfattning : Carbon nanotubes are one of the most promising building blocks for the developing field of nanoelectromechanics. Due to their unique electronic and mechanical properties, these all-carbon systems have been suggested for a range of applications where one wishes to utilse the coupling between mechanical and electronic degrees of freedom on the nanometer length scale.

14. Magnetodynamics of pseudo spin valves investigated using co-planar waveguide and spin torque ferromagnetic resonance techniques
Sammanfattning : 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 some aspects of these structures from the fundamental physics point of view using the spin torque ferromagnetic resonance technique (ST-FMR) and conventional broadband FMR technique.

15. Cooling of a Suspended Nanowire by an ac Josephson current
Sammanfattning : Nanoelectromechanical systems have been used for the exploration of the quantum limit of mechanical motion. There is hope that the quest for the quantum regime of these systems will shed light on fundamental questions in physics and lead to new quantum technologies. LÄS MER
