16. Dynamics of Quantum Correlations with Photons : Experiments on bound entanglement and contextuality for application in quantum information
Abstract : The rapidly developing interdisciplinary field of quantum information, which merges quantum and information science, studies non-classical aspects of quantum systems. These studies are motivated by the promise that the non-classicality can be used to solve tasks more efficiently than classical methods would allow. READ MORE

17. DESIREE: Instrumentation Developments and Hot Metal Cluster Decays
Abstract : This thesis presents instrumentation developments and measurements performed at the Double ElectroStatic Ion Ring ExpEriment, DESIREE, at Stockholm University. DESIREE operates at cryogenic temperatures ~13 K, with very low background pressures of ~10-14mbar, allowing the observation of stored ions to long times of tens of seconds and longer. READ MORE

18. The Curious Case of Hot Metal Clusters : Spontaneous decay of excited, small silver and copper cluster anions in DESIREE
Abstract : Clusters anions are complex systems which, when formed with high internal energies, can decay via fragmentation and/or electron loss and may also cool via photon emission (radiative cooling). By studying the spontaneous decay mechanisms of small metal clusters, we can gain insight into the structure and properties of these systems. READ MORE

20. Simple Models for Complex Nonequilibrium Problems in Nanoscale Friction and Network Dynamics
Abstract : This doctoral thesis investigates three different topics: How friction evolves in atomically thin layered materials (2D materials); How social dynamics can be used to model grand scale common-pool resource games; Benchmarking of various image reconstruction algorithms in atomic force microscopy experiments. While these topics are diverse, they share being complex out-of-equilibrium systems. READ MORE
