Abstract:
Topological Acoustics (TA) is revolutionizing the science of sound and extending its frontiers. The newly formed Science and technology Center (STC) New Frontiers of Sound (NewFoS) will realize the full benefits of the broad and extraordinary properties of TA. With TA we are looking at sound from a geometric point of view, we are looking at the landscape of sound, in other words at a soundscape. Examining the geometry of sound uncovers extraordinary properties which have been overlooked before now, and which will serve as foundations for innovative and impactful technologies in information processing, telecommunication and sensing. NewFoS integrative research revolves around three problem-driven projects. The first project exploits the analogies between TA and quantum mechanics in terms of superpositions and correlations between bits to overcome the fragility of current quantum computing technologies. TA eliminates echo through topological protection offering a path to the second project focusing on reducing loss and increasing functionality of acoustic radio frequency devices for >5G wireless technologies. The information contained in the geometry of sound waves enables the third project dealing with TA sensing of the environment. More specifically, we use seismic waves for real-time monitoring of thawing of permafrost in the arctic resulting from climate change. We will also discuss NewFoS pedagogical plans for a transdisciplinary education in TA.
