Here is a list of research projects for your students if they visit UWA. Note some of them would need to begin in February 2017, other could begin 7th Jan 2017.

1.  Modelling and testing of high performance vibration isolation systems for gravitational wave astronomy.

Supervisors: Professors David Blair, Ju Li, Chunnong Zhao

By combining precision electric discharge machining with finite element modelling of buckling structures, it is possible to design improved high performance vibration isolation systems required for improving gravitational wave detectors and improving the detection rate of binary black holes. This project will involve modelling and testing of such structures.

2. New materials for magnetic hydrogen gas sensing (experimental) - starting Feb 2017

Supervisor: Professor Mikhail Kostylev

Our group has recently shown that ferromagnetic resonance (FMR) in ferromagnetic (FM) films interfaced with non-magnetic palladium (Pd) films can be used for hydrogen gas sensing [1]. Early detection of leaks of hydrogen gas will be very important for ensuring safety of future hydrogen gas fuelled cars and car fuelling stations. So far, our research has focussed on cobalt as the material for the ferromagnetic layer. The goal for the proposed project is to investigate potential of iron and nickel as candidates for the ferromagnetic layer of the Pd/FM bilayer structure. 
The student will fabricate the bilayer films with our group's magnetron sputtering machine and study the rich physics behind the effect of hydrogen gas on magnetic properties of the structure with an advanced FMR setup available in our lab.

3. . Investigation of spin wave scattering from nanometre-size non-uniformities (theoretical) - starting Feb 2017

Supervisor: Professor Mikhail Kostylev

Spin waves in ferromagnetic films are a very promising object for usage in the next generation of computer logic [1] and in novel sensing applications [2,3]. Many of those applications will rely on scattering of spin waves from uniformities of magnetic environment of a film, as, for instance, in [1]. So far, the problem of calculation of spin wave scattering has been solved in 1 dimension only [4]. The goal of the proposed project is to attempt to solve a two-dimensional problem rigorously and (quasi)-analytically. It is anticipated that very interesting effects, such as formation of spin wave caustics [5] form the scattered spin wave field will follow from this solution.

4. Development Field Programmable Cavity Arrays

 Supervisor: Professor Michael Tobar

Physics and engineering make use of wide range of microwave cavities of different shapes and geometries specific to particular applications. To standardize cavity design and development approaches, recently, a method of creating Programmable Cavity Arrays have been proposed [1-3] (i.e. microwave analogues of FPGAs and FPAAs). It is based on re-entrant type modes in closed 3D metallic cavities and offers a high in-situ tunability. This project aim is to further develop the method both theoretically and experimentally. On the theoretical side, novel structures and possible programming algorithms will be investigated. The experimental part will be related to the development of electronic tuning using varactor diodes. Besides the technical applications, this type of cavity has potential applications for novel sensing technology and quantum computing.

5. Data Processing and Machine Learning - Starting Feb 2017

Supervisor: Professor Jingbo Wang

In this project we will examine several machine learning and optimisation techniques, which is a core component of our research in quantum deep learning.  It would be ideal if we could have two students working together on this project. 

6. Testing a power build-up cavity for an optical lattice clock. 

Supervisor: Associate Professor John McFerran

The UWA School of Physics is building a state-of-the-art optical atomic clock as part of a ground station for future space-clock missions.  It is designed to explore a number of aspects of fundamental physics; for example, the constancy of fundamental constants. The UWA clock is already in operation (the first of its kind in the southern hemisphere); however, one critical last stage needs to be implemented ?an optical lattice trap that is needed to maintain tight control of the centre-of-mass motion of the atoms.   The experiment has demonstrated trapping and cooling of ytterbium atoms to 20 micro-K in temperature.  The next step is to trap the cold atoms in an 'optical dipole trap' to produce a periodic array of atoms.   In this project the student will help develop the power build-up system needed for the atomic lattice  clock. They will have the opportunity to work on laser systems and become familiar with data acquisition systems and electronics.
