Nano Vacuum Channel Devices for Electronics and Ultrafast Nanophotonics
… radiation hardness, integrability, and ultrafast switching times. Planar NVC devices are ideal candidates for electronics that need to operate in harsh environments such as space. Moreover, recent work, some of which is discussed in this thesis, has demonstrated a rectified, field driven …

Femtosecond Laser Interactions In The Condensed Phase: Application to Transient Absorption and Materials Processing
… sub-10 fs duration and facilitate the study of ultrafast phenomena in chemical, biological and physical systems. The high field intensities inherent in these pulses, means that highly non-linear processes may be observed. Studies of solution phase transient absorption and femtosecond pulse laser …

Electronic excitation and atomic forces in optically excited group V semimetals
… phonon motion. The recent development of ultrafast optical spectroscopy has greatly advanced our understanding of these phenomena. However, many aspects of ultrafast phenomena are still poorly understood. For instance, experiments on a variety of different materials have shown that …

Ultrafast dynamics in quantum materials probed by time-and-momentum-resolved techniques
… in quantum materials give rise to intriguing phenomena, including magnetism and superconductivity. However, these interactions are often challenging to understand due to the intertwining of multiple degrees of freedom, such as charge, spin, orbital, and lattice. To fully understand such …

Optically induced ferro- and antiferromagnetic dynamics in the rare-earth metal dysprosium
… for the out-most long-ranging effect. Ultrafast ferromagnetic dynamics can be expected to base on the same origin, which however leads to demagnetization only in regions close to interfaces caused by super-diffusive spin transport. Dynamics due to local scattering processes of excited …
