1. Theoretical quantum optics with giant atoms
Sammanfattning : Giant atoms have emerged as new paradigm in quantum optics during the last decade. These are quantum emitters that couple to light—or other bosonic fields—at multiple discrete points, which can be spaced wavelengths apart. LÄS MER
2. Quantum optics with artificial atoms
Sammanfattning : Quantum optics is the study of interaction between atoms and photons. In the eight papers of this thesis, we study a number of systems where artificial atoms (here, superconducting circuits emulating the level structure of an atom) enable us to either improve on known concepts or experiments from quantum optics with natural atoms, or to explore entirely new regimes which have not been possible to reach in such experiments.

3. Quantum acoustics with superconducting circuits
Sammanfattning : The past 20 years has seen rapid developments in circuit quantum electrodynamics, where superconducting qubits and resonators are used to control and study quantum light-matter interaction at a fundamental level. The development of this field is strongly influenced by quantum information science and the prospect of realizing quantum computation, but also opens up opportunities for combinations of different physical systems and research areas.

4. Giant Dipole Resonances as Probes of Local Environment in Molecules, Clusters and Solidsl
Sammanfattning : In this thesis, I study effects of the local environment on the giant dipole resonances (GDR) in lanthanides and actinides. The effects of embedding in jellium, bonding in small molecules and incorporation into different fullerene systems are studied. LÄS MER
5. Quantum Electro- and Acoustodynamics in Waveguides
Sammanfattning : The study of light-matter interaction in superconducting quantum circuits has seen remarkable progress over the last $20$ years. By engineering artificial atoms, novel quantum phenomena have been demonstrated, and old ideas have come into a new light. LÄS MER
