The division of appliedphysics of the Commonwealth Scientific and Industrial Research Organization performs research in the physical sciences to benefit Australian industry and also staffs the National Measurement Laboratory, underpinning the Australian measurement system. CSIRO is the major government-funded research organization in Australia, employing approximately 7,000 people, based in 30 divisions, and whose interests range from the agricultural and livestock areas through prospecting, mining, and manufacturing to information and communication technologies. The general mix of work in the divisions includes a proportion of basic science and a significant involvement in contract research with relevant Australian *** division of appliedphysics is one of the oldest divisions and celebrates its 50th Jubilee in 1988. This year is also the 200th anniversary of European settlement in Australia and the 25th anniversary of the founding of the Australian Institute of physics. It was a busy year for the laboratory!Materials science research in the division developed from the needs of the standards research program, passed through a period of primarily basic research, and now concentrates on industrial research and the underlying basic research. Four areas which exemplify this progression toward applied research and development are described in this *** film research started in the division in the 1950s to produce optical coatings, driven by the requirements of a developing standards research program, and the needs of an astronomy program to study the surface of the sun spectroscopically.

Interacting crystalline SPT phases were first classified by Thorngren and Else through the crystalline equivalence principle, suggesting that a spatial group symmetry can be treated as if it were an internal symmetry group. Using techniques from topology, we elucidate how this principle holds for one of the proposals for the interacting bosonic case and yet fails for weak free-fermion phases. Lastly, we show how a variant of the principle does hold for strong crystalline free-fermion phases, showing that it is not necessary for the cohomology theory to be of Borel type.
We propose a predictor-corrector adaptive method for the study of hyperbolic partial differential equations (PDEs) under uncertainty. Constructed around the framework of stochastic finite volume (SFV) methods, our app...

Supercurrent flow can induce a nonvanishing spin magnetization in noncentrosymmetric superconductors with spin-orbit interaction. Often known as the nondissipative magnetoelectric effect, these are most commonly found at linear order in supercurrent flow. Here, we propose that a nonlinear superconducting magnetoelectric (NSM) effect can naturally manifest in magnet-superconductor heterostructures. In such platforms, NSM manifests as the spin polarization generated as a second-order response to a driving supercurrent. Strikingly, we find NSM survives centrosymmetry and is the leading-order magnetic response in a variety of magnetic materials that include both collinear magnets (e.g., d-wave planar altermagnet thin film-superconductor) as well as noncollinear magnets (e.g., kagome-superconductor systems). This renders NSM a powerful electric and nondissipative means of controlling magnetization in magnet-superconductor heterostructures, a promising platform for superconducting spintronics.
