Metamaterials for control of acoustic radiation forces. This project aims to investigate how sound waves exert forces on objects, and how these forces can be controlled by artificially engineered structures known as acoustic metamaterials. The project is expected to lead to a new understanding of acoustic radiation forces, and how they can be efficiently manipulated with high resolution. The expected outcome is a new capability for the measurement of delicate mechanical structures, which avoids ....Metamaterials for control of acoustic radiation forces. This project aims to investigate how sound waves exert forces on objects, and how these forces can be controlled by artificially engineered structures known as acoustic metamaterials. The project is expected to lead to a new understanding of acoustic radiation forces, and how they can be efficiently manipulated with high resolution. The expected outcome is a new capability for the measurement of delicate mechanical structures, which avoids the cost, complexity and side-effects of existing systems. This should benefit many high-tech areas, including inflatable space structures, micro-mechanical sensors and actuators and precise optical components, as well as biological areas such as the study of insect flight and communication.Read moreRead less
Nonlinear and tunable topological states of light and sound. This project aims to provide deep theoretical insights into the physics of electromagnetic and mechanical topological states by bridging fundamental concepts of optics, optomechanics and nonlinear physics.

This project aims to provide deep theoretical insights into the physics of electromagnetic and mechanical topological states by bridging fundamental concepts of optics, optomechanics and nonlinear physics. The rapidly expanding digital world calls for a new generation of photonic devices to transmit and process information without losses. Recently discovered topological phases open unique opportunities to realise topological states of light that are inherently immune to scattering losses. This multidisciplinary project aims to bridge fundamental topological physics with nonlinear nanophotonics and optomechanics by developing novel concepts of topological systems, dynamically tunable by nonlinearity. An expected outcome of this project is new approaches to control both light and sound dynamically in complex nanoscale structures, and uncover disorder-immune technologies for applications in on-chip communications and information processing.Read moreRead less
Topologically nontrivial electromagnetic states. Topological properties play a fundamental role in many physical phenomena. The best known examples are quantum Hall systems, where insensitivity to local properties manifests itself as conductance through edge states that is insensitive to disorder. While the traditional research focus has been on electronic systems, there has been a recent emergence of great interest in exploring topological orders with photons. Several novel intriguing theoretic ....Topologically nontrivial electromagnetic states. Topological properties play a fundamental role in many physical phenomena. The best known examples are quantum Hall systems, where insensitivity to local properties manifests itself as conductance through edge states that is insensitive to disorder. While the traditional research focus has been on electronic systems, there has been a recent emergence of great interest in exploring topological orders with photons. Several novel intriguing theoretical schemes have been proposed to explore topological orders in photonic systems, both in the linear and strongly interacting regimes. This project aims to develop innovative theoretical and experimental approaches to explore topologically non-trivial states, from microwaves to optical regimes.Read moreRead less

Summary
Optically controlled containers for experiments in soft matter. Nanotechnology has a promising future in the fabrication of small machines but exactly how these machines work is far less certain as they defy fundamental, classical thermodynamics. This equipment will allow Australian researchers to probe the energy dissipation of, and the work done by, small systems, including those of single molecules, colloidal crystals and membranes.
