Description

On behalf of the Australian Institute of Physics (AIP), it gives us great pleasure to invite you to participate in the 24th Australian Institute of Physics Congress, to be held at the Adelaide Convention Centre from 11-16 December, 2022. This year we are delighted to be co-locating with the Australian and New Zealand Conference on Optics and Photonics (ANZCOP), the 7th International Workshop on Speciality Optical Fibers (WSOF), and the Conference on Optoelectronlc and Microelectronic Materials and Devices (COMMAD).

The Congress will be held in Adelaide, South Australia, between Monday-Friday 12-16 December 2022. The venue for the Congress is the Adelaide Convention Centre, conveniently located on the picturesque banks of the Torrens Lake in the heart of the city.

The Adelaide Convention Centre is committed to providing a COVID Safe environment.

The optional pre-conference ANFF and 3D Printing workshops will be held at the North Terrace campus of the University of Adelaide on Sunday 11 December 2022.

        From Nonlinear Optics to High-Intensity Laser Physics

        The laser increased the intensity of light that can be generated by orders of magnitude and thus brought about nonlinear optical interactions with matter. Chirped pulse amplification, also known as CPA, changed the intensity level by a few more orders of magnitude and helped usher in a new type of laser-matter interaction that is referred to as high-intensity laser physics. In this talk, I will discuss the differences between nonlinear optics and high-intensity laser physics. The development of CPA and why short, intense laser pulses can cut transparent material will also be included. I will also discuss future applications.

        Abstract:
        We treat the virtual particle-anti-particle pairs in the vacuum as two level quantum systems with a transition energy of 2mc^2, forming a dielectric and a diamagnetic. The approach describes the linear response explaining the parameters appearing in Maxwell's equations and also the nonlinear response. This phenomenological model is largely compatible with quantum field theory, without leading to divergencies. The approach provides novel insight into the ubiquitous vacuum medium.

        Short Bio:
        Gerd Leuchs studied physics at the Universities of Cologne and Munich. His PhD-thesis dealt with the fine structure splitting of sodium Rydberg atoms. He received the Habilitation degree at the University of Munich on multiphoton processes in atoms. After stays in the USA and Switzerland, Gerd Leuchs became full professor of physics at the University Erlangen-Nuremberg in Germany. Since 2009 he was director at the Max Planck Institute for the Science of Light and since 2011 he is professor adjunct at the University of Ottawa. He is member of the German and of the Russian Academy of Sciences and holds honorary degrees from Danish Technical University and St. Petersburg State University. He won the 2005 Quantum Electronics and Optics Prize of the European Physical Society and the 2018 Herbert Walther Prize, a joint award by Optica (formerly OSA) and DPG. In 2012 he was awarded the Cross of Merit of the Federal Republic of Germany and in 2018 he was appointed a member of Bavaria’s Maximilian Order. Currently (2022) he is vice-president of Optica. His research spans the whole range from classical to quantum optics, with emphasis on the limits of focussing, on photon-atom-coupling and on quantum noise reduction of light.

        Silicon Photonic Quantum Computing – Towards Large-scale Systems

        Many efforts around the world are now pursuing the ambitious goal of utility-scale, fault-tolerant quantum computing. Consistent themes are emerging across the field, as teams attempt to scale from existing small systems to the millions of qubits needed for useful applications. Systems partitioning, manufacturability, cooling power, networking, and control electronics are recurring challenges across all qubit technologies.

In this talk we will give a broad overview of recent technical progress, framed against these major scaling challenges. We will describe progress at the micro, meso, and macro-scale, including high-throughput test, semiconductor manufacturing, device performance, integration, packaging, control, and cryogenic systems.

        From Quantum in Pictures to practical Natural Language Processing, Music, and understandable AI

        This talk requires no particular technical mathematics background, as I will talk entirely in terms of simple pictures. These are the pictures of my new book, "Quantum in Pictures" [1], which is aimed at the teenage enthusiast, and pretty much everyone else too - the book had a more technical predecessor [2].

        One finds the same pictures in natural language, and much of the high-level reasoning that goes on in our brain can be shaped according to those pictures. One consequence of this is that natural language really wants to live on a quantum computer, which is something that we meanwhile realised [3], and we have also made music with quantum computers [4]. All our software developed for doing so, lambeq and Quanthoven respectively, is freely available from GitHub, open-source, and well-documented and well-supported. You can have a go yourself!

        We show how these pictures also guide us towards a new form of natural language, one in which different languages all become the same. This in turns forms a new template for interpretable compositional AI.

        Active optical fibers that exhibit intrinsically low nonlinearities such SBS supression or increased TMI thresholds is the end research goal for many groups. Materially, these phenomena are well understood, as is the method to achieve the target thresholds.

        Temperature-dependent synchrotron absorption measurements of MgO:LiNbO3

        We report synchrotron absorption measurements for MgO:LiNbO3 over a wide range of wavenumbers and temperatures. Spectra reveal the existence of an unexpected mode at 3.15 THz at all temperatures which explains the crystal's difficulty of THz generation at higher frequencies.
