1. Fabry-Pérot based refractometry : development of a transportable refractometer for assessment of gas pressure
Abstract : A unified description of physical phenomena through measurement science is one of the foundational pillars in a global society. The International System of Units (SI) is the most widely used system of units and since its redefinition in 2019, all units encompassed by it are based on fundamental physical constants. READ MORE

2. Effects of disorder in metallic systems from First-Principles calculations
Abstract : In this thesis, quantum-mechanical calculations within density-functional theory on metallic systems are presented. The overarching goal has been to investigate effects of disorder. In particular, one of the properties investigated is the bindingenergy shifts for core electrons in binary alloys using different theoretical methods. READ MORE

3. The Jovian Plasma Dynamics and Composition Analyzer (JDC) for ESA's JUICE Mission
Abstract : This dissertation covers the development and calibration of the Jovian plasma Dynamics and Composition analyzer (JDC). JDC is together with five other sensors a part of the Particle Environment Package (PEP), one of the payloads of the European Space Agency's JUpiter ICy moons Explorer (JUICE) mission. READ MORE

4. Spin ice under uniaxial pressure and magnetic frustration in garnets
Abstract : Frustration is the inability to simultaneously satisfy all interactions. The interest in magnetic frustration has grown during the last decades. The research has among other findings been promoted by the discovery of spin ice which is a frustrated magnetic compound with an exotic ground state and unusual excitations. READ MORE
