09:00 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.

2 Friedrich-Alexander-Universität Erlangen-Nürnberg, Germany
3 Nexus for Quantum Technologies, University of Ottawa, Canada
4 Lakehead University, Thunder Bay, Canada
5 Universidad Complutense de Madrid, Spain

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.

09:00 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.

PsiQuantum has pursued a photonic approach, based on qubits implemented using optical photons propagating in lithographically fabricated waveguides. 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. We will also present new architectural results pertaining to fault-tolerant compilation.

Speaker: Prof. Jeremy O'Brien (University of Western Australia and PsiQuantum)

09:45 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.

18:45 Constraining Beyond The Standard Model Nucleon Isovector Charges

At the TeV scale, low-energy precision observations of neutron characteristics provide unique probes of novel physics. Precision studies of neutron decay observables are susceptible to beyond the Standard Model (BSM) tensor and scalar interactions, while the neutron electric dipole moment, $d_n$, also has high sensitivity to new BSM CP-violating interactions. To fully utilise the potential of future experimental neutron physics programs, matrix elements of appropriate low-energy effective operators within neutron states must be precisely calculated. We present results from the QCDSF/UKQCD/CSSM collaboration for the isovector charges $g_T,~g_A$ and $g_S$ using lattice QCD methods and the Feynman-Hellmann theorem. We use a flavour symmetry breaking method to systematically approach the physical quark mass using ensembles that span five lattice spacings and multiple volumes. We extend this existing flavour breaking expansion to also account for lattice spacing and finite volume effects in order to quantify all systematic uncertainties.

11:30 The Fabric of Space-Time

The general theory of relativity, presented by Albert Einstein in 1915, has been well tested over the last century, and has led to far-reaching consequences, most of which were foreseen by Einstein himself. Two notable exceptions were that he did not predict the prevalence of space-time singularities throughout general solutions of the Einstein field equation, and although he knew that gravitational waves were a prediction of his theory, he believed that they were far too small for humanity to ever possibly detect them. In this talk I will discuss aspects of my ongoing research related to these two central, and evolving, subfields of general relativity.

12:00 Silicon continues to surprise with potentially powerful new properties and applications

In recent years, it has been shown that silicon is not only the foremost electronic and photovoltaic material but can be structurally modified to dramatically enhance its properties and applications. This presentation highlights two such cases. First, silicon has been shown to possess up to 12 crystalline phases in addition to the equilibrium diamond cubic structure that has fueled the silicon chip revolution. These phases can be accessed by applying pressure, by using a diamond anvil cell, by indentation pressure, or even by femtosecond laser irradiation. Many of these phases are metastable at room pressure and temperature, and some have been shown to have interesting narrow bandgap semiconducting, as well as superconducting properties. Although such properties have not yet been exploited commercially, mainly as a result of scale-up limitations, they show considerable promise for novel applications. The second part of this presentation addresses a further area of novel silicon research, namely hyper-doping of silicon with transition metals to form dilute silicon alloys, that has been demonstrated to have important applications for near-infrared photodetectors. One such case, gold-hyperdoped silicon, possesses an intermediate band within the silicon bandgap that can be exploited for intriguing optoelectronic applications.

16:45 Search for Dark Matter in Invisible Higgs Decays with the ATLAS experiment

The nature of dark matter is still unknown and it is one of the key questions in particle physics. Many beyond the Standard Model theories predict the production of dark matter particles in the decays of the Higgs boson. As dark matter particles do not interact with the detector, they would be invisible to the detector and can only be probed using the presence of missing transverse momentum.

With full Run-2 data, the ATLAS experiment has performed six independent searches for dark matter in the invisible decays of the Higgs boson, each focusing on a different production mechanism and the final state. In this poster, I will present the results from the combination of these searches.

14:00 Teaching and Learning Modern Physics: Quantum Physics and / Relativity

Format: 20 minutes workshops by the university professors
Description: Modern physics requires an adequate use of models and a deep conceptual understanding of the underlying abstract ideas. The Physics curriculum in high schools and introductory university courses contains, at best, a passing reference to 20th Century physics. How have teachers and students adapted their conceptual frameworks towards incorporating the highly non-classical issues of modern physics? Do they appreciate the topics of interest to contemporary physicists, the contribution of physics to modern thought or the connection between the Physics they learn and modern technology? Examples include the Laser, Quantum technologies, LED, Large Hadron Collider, gravitational waves,
How can we stimulate greater interest and encourage our students to pursue their studies of physics further?

Description: Will Australia be ready for the next generation of space innovations?
Space science and technologies is one of the most rapidly-growing, highly-diverse areas in Australia that needs new people in it. It’s a growth industry and we need Australians to contribute to it. That takes focus and investment. Space is more accessible now than it has ever been. We can have small and large private companies building and launching systems into space that can monitor the Earth and space environments. Australia would benefit from strong investment in space science research and development. One of the most exciting things about space science is the amazing technologies and applications that we can create to improve life on Earth. The Australian Academy of Science has released a 10-year plan for space science, calling on the federal government to prioritise innovation while protecting our sovereign interests.
Each panellist will present their views in the context of their field and address:

18:45 Microwaves with a twist: helical resonators for a new form of ultra-light darkmatter detection

Chirality is a fundamental property in many physical systems ranging from particle physics, topological and quantum systems, complex molecules and chiroptical phenomena. Many of these phenomena occuras surface states, at high energy and frequency, due to complex meta structures or plasmonic systems,which inevitably add loss. In this work we realise a new class of resonator, the Anyon cavity resonator,based on twisted and Möbius structures, which exhibit bulk chiral modes at radio frequencies with near unity helicity. We show that the modes naturally couple strongly to ultra-light dark matter axions with near unity form factors, equal to the square of the mode helicity. Ultra-light axions have been shown to solve the Standard Model strong Charge-Parity problem [1] and could account for the entire dark matter density of the universe [2], and are usually searched for using putative axion interactions with gluons and neutrons [3]. In contrast, ultra-light dark matter axion experiments proposed through the axion-photon chiral anomaly require two near degenerate photon modes, and are limited by how close in frequency the two modes can be tuned [4]. We show, due to the unique resonator properties, modes with non-zero helicity interact with the ultra-light axions causing an amplitude modulation, without the need for two seperate photon modes. This not only drastically reduces the complexity, but also opens up the possibility of utilising low loss superconducting resonators [5], allowing sensitive searches in the ultra-light mass range of 10−22to 10−14eV.

18:45 UV emission from lanthanide-doped upconversion nanoparticles in super-resolution microscopy: potential for cellular damage

“The upconversion nanoparticles (UCNPs) have recently attracted great attention as a fluorescence probe for use in super-resolution microscopy (SRM). This is due to the advantages of UCNPs over other fluorescence probes such as fluorescent proteins owing to their unique optical properties, lack of photobleaching and sharp emission peaks. However, the ultraviolet (UV) light that can be emitted from the UCNPs has been overlooked in most studies. The potential cell photodamage caused by UV light has been proven a limiting factor for in-vivo analysis. Here, UCNPs synthesised with eight commonly used combinations of Yb/Tm and Yb/Tm/Gd doped UCNPs were excited by pulsed and continuous wave (CW) lasers to evaluate their UV emissions. The UV-A and UV-B ratios were measured relative to the blue light emission at 475 nm which is traditionally used for imaging during SRM. We demonstrate that most samples generated UV light and that the dopant concentration has a key role in generating UV emissions. In addition, the usage of a pulse or CW laser for a similar UCNP sample can lead to large variations in the amount of UV emission produced. The results from this study highlight the importance of upconversion dopant concentration design as well as undertaking fluorescent analysis on synthesised UCNPs before their use to prevent unwanted cell photodamage during in vivo images taken with SRM.”
