1. MATTER-ANTIMATTER INTERACTIONS : The hydrogen-antihydrogen system and antiproton-matter interactions
Sammanfattning : Ever since antiparticles were discovered their nature has been something of a mystery. They were postulated to be identical to regular particles except for having opposite charge, but this would imply that an equal amount of antiparticles and particles should have been created at the beginning of time.

Sammanfattning : The discovery of graphene in 2004 has led to a surge of activities focused on the theoretical and experimental studies of materials hosting linearly dispersive quasiparticles during the last decade. Rapid expansion in the list of materials having similar properties to graphene has led to the emergence of a new class of materials known as the Dirac materials. LÄS MER
Sammanfattning : This dissertation examines the importance of individual work motivation for two crucial dimensions of inequality: work learning and labor market performance. The first dimension relates to learning activities at work, and the second to wage attainment and knowledge-oriented task assignment. LÄS MER
