1. Majorana Representation in Quantum Optics : SU(2) Interferometry and Uncertainty Relations
Sammanfattning : The algebra of SU(2) is ubiquitous in physics, applicable both to the atomic spin states and the polarisation states of light. The method developed by Majorana and Schwinger to represent pure, symmetric spin-states of arbitrary value as a product of spin-1/2 states is a powerful tool that allows for a great conceptual and practical simplification.

2. Quantum Dynamics of Molecular Systems and Guided Matter Waves
Sammanfattning : Quantum dynamics is the study of time-dependent phenomena in fundamental processes of atomic and molecular systems. This thesis focuses on systems where nature reveals its quantum aspect; e.g. in vibrational resonance structures, in wave packet revivals and in matter wave interferometry. LÄS MER
3. Coherent Multidimensional Spectroscopy: Development of Efficient Data Acquisition and Analyses of Quantum Dot 2D Spectra
Sammanfattning : Coherent multidimensional spectroscopy (CMDS) is the most complete nonlinear optical technique based on the interaction of multiple short laser pulses with matter. It has grown to play a significant role in studies of optoelectronic materials and pigment protein complexes. LÄS MER
4. Det moderna åldrandet : Pensionärsorganisationernas bilder av åldrandet 1941-1995
Sammanfattning : The aim of the dissertation is to describe images of old age in the magazines of Sweden’s two largest pensioner organizations, and explain the character of those images in relation to the temporal contexts of the organizations and their aim to act as the representatives of pensioners. The study is based on the 329 and 330 magazines (1941–1995) that the organizations have submitted to attract members and spread political messages. LÄS MER
5. Om tolkningen av traktater
Sammanfattning : In the relations between states interpretation of treaties is an everyday issue. When an agent of state confers a meaning on a treaty text, the ensuing interpretation is talked of as being legally either correct or incorrect. This is a distinction made possible thanks to the existence of certain norms. LÄS MER
