Abstract:
The usual understanding of solid-liquid interaction is that near-surface effects predominate, while further away, the two media are considered independent. Over the past few decades, it has been shown that confined liquids, when interacting with so-called adherent surfaces, behave like solids, indicating a long-range vibrational character. Do these vibrations interact with those of the solid substrate?
This PhD thesis examines this interaction using precise experimental methods (synchrotron radiation and neutron scattering). We demonstrate the impact of flowing liquid on long-range vibrations in solids. We have therefore identified a new type of interaction driven by flow, which we interpret as indicative of solid-like vibrational properties of the liquid and its phononic coupling with the substrate.

Attached you will find a map of the official parking lots. As the plateau is under construction, there is space to park around it, in a somewhat ‘wild’ manner.
