Instrumentation for the era of gravitational wave science. This project aims to study noise sources that limit the low-frequency performance of gravitational wave antenna: thermal noise, quantum radiation pressure noise and Newtonian noise. Gravitational wave detection is a new way in which to observe our universe.

This project aims to study noise sources that limit the low-frequency performance of gravitational wave antenna: thermal noise, quantum radiation pressure noise and Newtonian noise. Gravitational wave detection is a new way in which to observe our universe. Although detectors such as advanced LIGO (Laser Interferometer Gravitational-Wave Observatory) should detect gravitational waves, further sensitivity improvement, particularly at low frequencies, will be needed to provide event rates necessary for astronomy. Expected project outcomes will support the development of the first free mass interferometer to operate at 120K using silicon optics, a vital facility for the world community. Pushing the boundaries of measurement may also drive innovation in optical sensing with potential applications in defence, security and exploration.Read moreRead less

Precision laser levitation for quantum metrology and gravitational sensing: This fellowship project aims to levitate macroscopic objects using only laser beams, to provide a new tool to test physics theories. Strong laser beams can exert sufficient force to counteract gravity and make an object levitate. In contrast to other forms of levitation, laser levitation is scatter-free and can preserve system coherence. It has superior optical and mechanical quality factors and complete information of the system dynamics is retained. This allows laser levitation to be turned into a highly controllable and ultra-sensitive device capable of detecting minute environmental changes. This research aims to probe the relationship between quantum and gravitational physics and develop laser levitation into a precision instrument for the sensing of gravity. Laser levitation has the potential to be developed into technology for mineral exploration and environmental sensing.Read moreRead less
Coherent Laser Levitation for Precision Sensing and Enabling Science. When light collides with matter, it may exert a force called radiation pressure. This project aims to use radiation pressure to levitate a small mirror. Using a tripod of laser beams, it is possible to levitate and trap the mirror in a stable position. Radiation pressure has been used before to levitate, but previous work has always involved scattering light from the levitating object. This project proposes the use of a high q ....Coherent Laser Levitation for Precision Sensing and Enabling Science. When light collides with matter, it may exert a force called radiation pressure. This project aims to use radiation pressure to levitate a small mirror. Using a tripod of laser beams, it is possible to levitate and trap the mirror in a stable position. Radiation pressure has been used before to levitate, but previous work has always involved scattering light from the levitating object. This project proposes the use of a high quality mirror, allowing the collection of the reflected light and the accurate measurement and control of the position of the mirror as it floats on the laser beams. Using the unique properties of the floating mirror, it will be possible to search for signatures of quantum gravity and develop tools for ultra-precision metrology.Read moreRead less
