1. Relativistic light-matter interaction
Abstract : During the past decades, the development of laser technology has produced pulses with increasingly higher peak intensities. These can now be made such that their strength rivals, and even exceeds, the atomic potential at the typical distance of an electron from the nucleus. READ MORE

2. Light-Matter Interaction and Quantum Computing in Rare-Earth-Ion-Doped Crystals
Abstract : In this thesis, crystals of yttrium orthosilicate (Y2SiO5) that are randomly doped with another rare-earth element, such as praseodymium (Pr), europium (Eu), or cerium (Ce), are investigated with lasers locked to ultra-stable cavities using the Pound-Drever-Hall locking technique. Many of these rare-earth elements have long-lived 4f-4f transitions, hundreds of microseconds to a few milliseconds, with even longer ground hyperfine lifetimes of up to several days. READ MORE

3. Investigations of Strong Light-Matter Interactions in Nanophotonic Systems
Abstract : Noble metal nanoparticles can support localized surface plasmon resonances (LSPR), thus behaving as open optical resonators. Outstanding optical properties as well as a subwavelength mode volume make plasmonic nanoparticles a promising platform for enhanced light-matter interactions. READ MORE

4. Strong Light-Matter Interactions and Formation of Hybrid States at the Nanoscale
Abstract : Noble metallic nanoparticles, which support localized surface plasmon resonances (LSPR), offer a variety of potential scientific and industrial utilizations. Due to their remarkable ability to confine light at nanoscale dimensions, far below the optical diffraction limit, plasmonic nanoparticles enable intricate light manipulations, which may be performed and exploited for a wide range of future revolutionary applications.

5. Excited state dynamics in the strong coupling regime
Abstract : Strong exciton-photon coupling exhibits the possibility to modify photophysical and photochemical properties of organic molecules without changing their structure. This is due to the formation of hybrid light-matter states, called polaritons, which are created when the strong coupling regime is achieved. READ MORE
