13:00 - SEMINAR - Quantum gravity on a quantum computer? More Information
Quantum information theoretic tools could be used to study the most basic physical phenomena. For example, measurements of quantum entanglement allow one, in principle, to detect curvature. If curvature can be expressed completely in terms of entanglement, this opens up the prospect that quantum gravity could be simulated on a quantum computer. Mathematical side results yield surprising answers to questions of the type famously described by Kac's as "Can one hear the shape of a drum?"

13:00 - SEMINAR - The sound of a vase, and the quantum universe More Information
The two deepest theories of nature, quantum theory and general relativity, long considered esoteric, are nowadays at the heart of everyday life, for example in all sorts of electronics and in GPS geo- location.

New areas of applications, such as quantum biology, quantum computing and quantum communication via satellites are on the horizon, and they too have the potential to change our lives.

Not all is well with these two theories, however: While general relativity is great for understanding the universe on big scales, it describes atoms incorrectly. Quantum theory gets atoms right but it cannot correctly describe the expansion of the universe.

Much effort is therefore going into the development of one unifying theory of “quantum gravity” that applies in all circumstances. These studies concern the deepest mysteries of nature. For example, the universe is thought to have arisen from a quantum fluctuation and it is likely that the fabric of spacetime still continually somewhat vibrates due to small quantum vacuum fluctuations.

Along the way, studies into these questions produce surprising mathematical side results. For example, as I will explain, it recently turned out that the mere sound of a vibrating object such as that of a vibrating vase can give away all details of the shape of the vase.

13:00 - SEMINAR - HPC Seminar: Why HPC is crucial to understanding how galaxies form More Information
Supercomputer simulations have played a transformative role over the last 30 years in establishing the paradigms of the growth of cosmic structure and galaxy formation. Theoretically they allow us to tackle problems that are otherwise intractable analytically, such as predicting the structure of the cosmic web and the internal properties of galaxies. Observationally they allow us to build virtual universes that allow us to interpret the results of large galaxy surveys. I'll review what goes into one of these simulations, explaining why and how supercomputers have proven to be crucial. I'll also highlight key predictions from simulations and identify areas where more work is needed as we enter the era of SKA-science.

15:30 - SEMINAR - Pulsars and Gravity More Information
Pulsars are extraordinarily good clocks. This property has been exploited in a wide range of applications ranging from studying the interiors of neutron stars to testing theories of gravitation. Many pulsars, especially millisecond pulsars, are in orbit around another star, providing a near-ideal gravitational laboratory. The original binary pulsar, PSR B1913+16, discovered by Hulse and Taylor in 1974, has provided the first observational evidence for the existence of gravitational waves (GWs) and has verified that Einstein’s general theory of relativity is an accurate theory of gravitation. The Double Pulsar (PSR J0737-3039A/B), discovered at Parkes, is an extraordinary system that not only gives new insight into magnetospheric and pulse emission physics, it also an unrivalled system for testing gravitational theories. Direct detection of gravitational waves is a major goal of current astrophysics. A Pulsar Timing Array (PTA) can in principle give a direct detection of GWs at nanohertz frequencies. A secondary goal of PTA projects is the establishment of a “pulsar timescale” which, over long time intervals, may be more accurate than the best available timescales based on atomic clocks. Since mid-2004, the Parkes Pulsar Timing Array (PPTA) project has been making regular timing measurements of 20 millisecond pulsars with steadily improving precision. While we do not yet have a significant GW detection, our current upper limit seriously constrains standard models for galaxy evolution and formation of super-massive black holes in galaxy cores. In collaboration with the European and North American PTAs we have formed the International Pulsar Timing Array (IPTA) to enhance progress toward PTA goals.

16:00 - SEMINAR - Moving-base Gradiometry without Gradiometers: Mission Impossible? More Information
Devices called GRADIOMETERS are well known instruments which have been designed for measuring the first spatial derivatives of physical fields (gravitational, magnetic, electromagnetic..). Moving-base gradiometry is an extremely challenging multi-discipline technology area that has been declared as a "holy grail" for applications like geophysical prospecting for oil & gas, minerals, water and for some other non-geophysical applications. This talk is about another option for measuring gradients in motion without using gradiometers as such. In the first look it is a Mission Impossible. However, new emerging technologies provide a basis for making this Mission Possible. I will describe how collaboration between The Australian International Gravitational Research Centre and the Centre for Gravitational Experiments of the Huazhong University of Science and Technology (Wuhan, China) has led to a new quest for this exciting new possibility.

16:00 - SEMINAR - Long Baseline Neutrino Experiment More Information
Over the past two decades we have made significant progress in our understanding of the fundamental nature of the elementary particle, called the Neutrino. The Long-Baseline Neutrino Experiment (LBNE) is a broad scientific program being developed in the United States as an international project to further study the neutrino particle. LBNE consists of an intense neutrino beam produced at Fermi National Accelerator Laboratory (Fermilab), a highly capable set of neutrino detectors on the Fermilab campus (Near Detector), and a large underground liquid argon Far Detector at Sanford Underground Research Facility (SURF) in the state of South Dakota. LBNE will make detailed studies of neutrino oscillations including measurements of the mass hierarchy and CP violation that take advantage of the 1300 km baseline. At the far site, the large underground detector will open a new window to the search for nucleon decay, supernova neutrinos, and interesting astrophysical phenomena. This talk will give an overview of our present understanding of neutrino physics the plans for the LBNE experiment.

13:00 - SEMINAR - A computational productivity toolbox: applications to nanomagnetism and computational science More Information
Virtually all branches of science have profited from the vast increase in computational power in recent decades. Yet, given that scientists are rarely trained as programmers, there is often a substantial barrier to harnessing this power and it is easy to lose track of results or get lost in data analysis. In my own work I study nanomagnetic systems where the interaction of multiple forces on different length scales leads to frustrated behaviour and complex dynamics. Despite this complexity, intense worldwide effort is directed towards the application of nanomagnetism in fields ranging from data storage to nanoscale sensing. From a computational point of view, nanomagnetic systems present huge challenges, both in terms of efficiently solving the underlying differential equations (especially in a finite-element framework), and in terms of subsequent data analysis, e.g. exploring large parameter spaces.

Guided by showcase examples from my own research on nanomagnetic and spintronic systems, I will give a hands-on, informal presentation of a few tools for efficient scientific computation, data analysis, and result documentation which I feel can be useful to a wide community of people. These will include: the IPython notebook (an interactive computational/documentation environment with optional parallelisation), FEniCS (a high-level finite-element framework for efficient, automated solution of differential equations) and Sumatra (an "automated electronic lab notebook for computational projects, with the aim of supporting reproducible research").

My hope is to inspire a wider inter-disciplinary discussion where people share thoughts about available tools and workflows that do (or don't) work for them.

Max is a theoretical mathematician-turned-computational physicist, doing his PhD at the Institute of Complex System Simulation (ICSS) at the University of Southampton, UK, and has a special interest in exploring how to make scientific research more reproducible and openly accessible. Max's stay at the School of Physics thanks to a UWA Research Collaboration Award. He is being hosted by the Spintronics and Magnetisation Dynamics Group and is working on applications of spintronic devices to biological sensing.

16:00 - SEMINAR - First-Principles Computational Thermochemistry: Theory and Applications More Information
During the past decade, computational chemistry has had an increasingly important impact on almost all branches of chemistry as a new approach for solving chemical problems at the molecular level and in obtaining information that is not accessible by experiment (e.g. in investigations involving transient, reactive, toxic, rare, or hypothetical species).

Theoretical methods have now been refined to the point where, for medium-sized systems with up to ~50 non-hydrogen atoms, they can determine very accurate molecular structures, reaction energies, barrier heights, spectroscopic constants and electrical properties.

First-principles thermochemical methods, such as Wn theories,1 combine large-scale electronic structure calculations with sophisticated extrapolation techniques to achieve unprecedented accuracies in thermochemical predictions. I will briefly review the Wn theories and show that they can reproduce the most accurate experimental thermochemical data with a 2σ uncertainty of under 1 kJ mol–1.1 For spectroscopic constants, Wn methods afford predictions with near-spectroscopic accuracy (i.e. 2σ uncertainty of ~1 cm–1).2 I will also present recent theoretical advances that extend the applicability of these theories to larger systems.3 Finally, some illustrative applications to water clusters,4 water-catalyzed proton-transfers,5 DNA bases,3 amino acids,6 tetrapeptides,7 corannulene8 and C60 will be given.
