DS 27: New Twists for Nanoquakes on a Chip - Emerging Applications of Surface Acoustic Waves in Condensed Matter Physics (Focussed Session): Session I

Donnerstag, 15. März 2018, 09:30–13:15, H 2032

Surface acoustic waves (SAWs) with gigahertz frequencies and micrometre size wavelength can be elegantly generated using piezoelectric transducers fabricated with standard integrated circuit technology. Their small propagation velocity, tight surface confinement, as well as low susceptibility to decoherence and dissipation have been exploited over the past decades in numerous devices, in particular for electronic and optical signal processing. Today, the interaction of SAWs with electrical, optical, magnetic, and mechanical excitations in condensed matter is a highly active field of research. It is driven by the vision to harness the power of this technique in a broad spectrum of emerging applications including advanced sensors, the control of magnetization and collective excitations, as well as the coherent interactions between charge and spin excitations, photons, and phonons down to the fundamental level of single quanta. We propose a symposium that brings together experts for emerging and future applications of surface acoustic waves. For the proposed symposium we have identified potential speakers covering the large palette of fields which this versatile technique is successfully applied or currently evolving towards. These encompass nanoscale acousto-optic integrated circuits and plasmonics, the control of single quantum systems and collective excitations in hybrid systems. Because the proposed symposium covers a wide range of frontier research in which SAWs are employed with greatest success, it will serve as an ideal platform for scientific exchange. Thus, it aims to foster new interactions between the different scientific communities. Its most important goal is to introduce this exciting field of research to the many young Masters and PhD students, and postdocs attending the joint DPG-EPS Spring meeting and gives them the opportunity to present contributed talks at the symposium or associated sessions.
