1. Waves in space plasmas : Lower hybrid cavities and simple-pole distribution functions
Abstract : Waves are a fundamental feature in many parts of physics, since they transport energy without transporting matter. This is the case also in space physics. Waves are responsible for energy transport both between different parts of space and between different particles in the space plasma. READ MORE

2. Modelling and measuring transport in fusion plasmas
Abstract : In the present thesis we consider theoretical and experimental aspects of the turbulent transport which is a crucial issue in fusion plasma physics.Experimental observations and gyrokinetic simulations show that collisions strongly influence the turbulent flux of particles. READ MORE

3. QED and collective effects in vacuum and plasmas
Abstract : The theory of quantum electrodynamics (QED) was born out of an attempt to merge Einsteins theory of special relativity and quantum mechanics. Einsteins energy/mass equivalence together with Heisenberg's uncertainty principle allows for particle pairs to be spontaneously created and annihilated in vacuum. READ MORE

4. Collisional effects and attosecond diagnostics in laser-generated plasmas
Abstract : When matter is radiated by laser light of extreme intensity, it is rapidly ionized, thereby forming a plasma. Such laser-generated plasmas can be used as sources of energetic particles and radiation, or to study astrophysically relevant phenomena in the laboratory and the behavior of matter under extreme conditions.
