1. Quantum Optics and Waveguide Quantum Electrodynamics in Superconducting Circuits
Abstract : Waveguide circuit quantum electrodynamics (waveguide circuit QED) studies light-matter interaction with superconducting circuits in one dimension. In circuit QED, natural atoms are replaced by superconducting qubits consisting of a non-linear Josephson junction, resulting in an anharmonic energy spectrum just like real atoms. READ MORE

2. Electron transport properties of graphene and graphene field-effect devices studied experimentally
Abstract : This thesis contains experimental studies on electronic transport properties of graphene with the Aharonov-Bohm (AB) effect, thermopower (TEP) measurements, dual-gated graphene field effect devices, and quantum Hall effect (QHE). Firstly, in an effort to enhance the AB effect in graphene, we place superconducting-metal (aluminium) or normal-metal (gold) mirrors on the graphene rings. READ MORE

3. Growth of ZnO/GaN distributed Bragg reflectors by plasma-assisted molecular beam epitaxy
Abstract : This thesis describes epitaxial growth of ZnO/GaN distributed Bragg reflectors by hybrid plasma-assisted molecular beam epitaxy on GaN(0001). The unique hybrid approach employed the same growth chamber for continuous growth of both ZnO and GaN without exposing the layers to the ambient conditions. READ MORE

4. Quantum optics with artificial atoms
Abstract : 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.

5. Free-space cavity optomechanical systems on a chip with III-V heterostructures
Abstract : Cavity optomechanics examines the mutual interaction between light and mechanical motion for controlling mechanical resonators down to the quantum regime. A major challenge in the field of cavity optomechanics remains accessing a strong interaction between the light field and mechanics on the level of single quanta. READ MORE
