16. A Trilogy of Mass A=61 : Superdeformed Structures, Exotic Decay, and Isospin Symmetry
Sammanfattning : Three nuclei with mass number A=61 have been studied using four fusion-evaporation experiments carried out at the Oak Ridge, Argonne and Lawrence Berkeley National Laboratories. Normally deformed states in 61Ga were for the first time ever explored and in addition the experimental knowledge of the mirror nucleus 61Zn was extended. LÄS MER
17. Mesoscopic thin film superconductors - A computational framework
Sammanfattning : Motivated by experiments on superconductors in the microscopic regime and the realization of small superconducting devices such as qubits, we initiate a computational project in the form of a numerical simulation package to model and predict the behavior of these type of systems. It is a multidisciplinary endeavor in that it employs theory, computational science, software design, and to some extent new visualization techniques. LÄS MER
18. Family symmetries and radiative corrections in multi-scalar extensions of the Standard Model
Sammanfattning : The four articles contained in this thesis all concern aspects of model building beyond the Standard Model (BSM). While Paper I mainly serves as a ``tool paper'' in which the results can be used to simplify certain calculations of one-loop effects from new heavy particles, Paper II--IV all deal with consequences of family symmetries in several BSM scenarios.

19. Applications of Soft X-Ray Spectroscopy
Sammanfattning : Soft X-ray emission spectroscopy is an old experimental technique that has seen a strong revival since the advent of new high brilliance soft X-ray sources in the shape of synchrotrons. This thesis covers a range of applications where soft x-ray techniques have been applied. LÄS MER
20. Defects, renormalization and conformal field theory
Sammanfattning : Defects in quantum field theories appear in many different contexts and are of great physical interest. Among other things, defects are used to describe the Kondō effect in condensed matter, confinement in quantum chromodynamics, Rényi entropy in quantum information and cosmic strings in string theory.
