Roslon, I.E. (author)Nanoscale forces from natural phenomena are hard to measure. It is not insofar that we lack the ability to measure such small forces. On the contrary, nanotechnology offers a wide spectrum of techniques that allow us to sense at this scale. However, many natural systems are subject to a noisy environment or need to be surrounded by liquid to...doctoral thesis 2023

Noordam, M.L. (author)In this thesis, we explore the interaction between multiple optical light fields. Although these light fields can interfere with each other in a vacuum, actual interaction can only occur in a medium. This interaction can be amplified in materials with nanoscale dimensions such as a monolayer of WS2 and metallic nanostructures. The shapes of...doctoral thesis 2023
