Surfaces form the boundary between two media, for example, between a solid body and a gas. A detailed understanding of effects near surfaces is important for many challenges in research and technology, ranging from heat transfer to the controlled deposition of solid-state quantum emitters on substrates. Within QUANTSURF we will explore novel experimental techniques for the study of near-surface effects. These will take advantage of the great level of control available for laser-cooled trapped atoms and, e.g., enable studying the coherent preparation of quantum-adsorbed atom-surface states. The results of this project will yield insights into surface-induced decoherence effects, open up pathways to fully passive traps for neutral atoms, and start bridging the gap between solid-state quantum optics and cold atom physics.
