Title: ‘Attoclock’ experiments on atomic and molecular hydrogen

Abstract: This thesis describes strong-field ionization experiments on atomic and molecular hydrogen using an ultrashort-pulse laser source and a sophisticated electron/ion detection setup called a reaction microscope (REMI). It aims at benchmarking strong-field physics with the help of precision measurements performed on the simplest atomic (H) and molecular (H2) systems. This work resulted in a definitive resolution of a long-standing controversy on measurement, value and interpretation of quantum tunneling time – determining that electron tunneling in atomic hydrogen is instantaneous within experimental precision (tunneling time is less than 1.8 attoseconds, or 1.8×10-18 seconds) and ruling out all previously proposed theoretical definitions of tunneling time.

organic research creates excitement for QLD students

The John Mainstone Youth Lecture Tour has wrapped up for another year after a successful tour!

Pegah poses for a self with the students of All Hallow’s School in Brisbane

Our 2019 John Mainstone Youth Lecturer was Dr. Pegah Maasoumi, a postdoctoral research fellow in the ARC Centre of Excellence in Exciton Science at the University of Melbourne. The John Mainstone Youth Lecture Tour took Pegah and her presentation: ‘My organic Research’, to 12 Queensland schools from the Sunshine Coast, Gladstone, Rockhampton, Brisbane to Toowoomba where she inspired and engaged the students with her exciting research and her journey as a scientist.

Pegah talked to more than 600 students in years 10-12, revealing the secrets behind foldable mobile phones, Ironman’s suit and next generation of solar windows. She told the story of her journey as a scientist and enlightened the students about the excitement and opportunities with a career as a Physicist.

All Hallow’s studens and teachers with Dr Pegah Maasoumi.

Pegah says: “no doubt, one of the highlights of my tour was the way students engaged with my research and story. The questions and ideas they shared during the talk, and all the promising feedback I got from their teachers, strongly suggest that they are considering science and Physics as career path. I am also very happy to be an organic example for them that a physicist is not just an old man with a fuzzy hair who works with forces. I like to think, they are now not picturing us as clumsy Big Bang Theory Physicists but more of capable Tony Stark version.”

With students from Padua College, Brisbane.

“Their questions totally blew my mind” Pegah said, “one of the very common questions was, ‘why are we not using solar more?’ and ‘still our politicians insist on burning coal?’ That question for me was pure joy to see. Not only are we promoting and fostering future scientists, but perhaps smarter politicians and better future for Australia.”

St Aidan’s Anglican School

Pegah believes the tour was very successful and nothing can be more effective than exposing our kids to living examples and questions out there. “I am absolutely grateful for this experience and I would love to see one of those bright girls as future John Mainstone Youth Lecturer and custodian of our worldwide famous pitch drop experiment.”

How Neutrons will save the world in brisbane

How Neutrons Will Save the World!

Women in Physics lecture Tour, 15th August, 2019.

This year’s Women in Physics Lecturer, Dr Helen Maynard-Casely is traveling around the country to tell us how neutrons will save the world! While in the area visiting schools, Helen will be at the University of Queensland, St Lucia campus on the 15th August talking to us about her research in more detail.

Where: Room 03-206

When: 1pm – 2pm 15th August, 2019.

We hope to see you there!

In the meantime, check out what Helen will be chatting about:

Exploring the materials of the solar system with Australia’s central facilities

Our solar system contains a great array of small planetary bodies that show remarkable variability in the chemistry, and subsequent materials, that form on their surfaces.  From sulfuric acid hydrates that are spattered on Europa, to organic minerals that fall in flurries on Titan to the plastic solids of methane and nitrogen on Pluto.

Sadly we’re yet to scoop any sample of these planets and bring them home, however informed by spectral observations from space missions such as Galileo, Cassini and New Horizons, we can re-create their surface chemistries and conditions in the lab.  What this has revealed that despite the ‘simplicity’ of the chemistry involved the surfaces are likely to be made up of a large array of materials with potentially planet-shaping properties. 

I’ll overview some of the materials we’ve found, and why central facilities (like the OPAL neutron source and Australian Synchrotron) have been crucial for this work.  Hopefully, I’ll also show how this is very much a growing business, and with new exoplanets being discovered daily there is still a wide range of materials that need to be investigated.

Title: Nonlinear optical properties of ZnO and ZnO-Au composite nanostructures for nanoscale UV emission

Abstract: This thesis investigates the nonlinear optical properties of ZnO and ZnO-Au composite nanostructures. For applications such as photodynamic therapy, it is desirable to use nanoparticles to generate localised UV emission while illuminating them with visible or infrared light. This is possible using nonlinear optical processes such as two photon absorption. Nonlinear optical processes however, are extremely weak, so this work investigates the potential of increasing the efficiency of two photon absorption in ZnO nanoparticles by coupling them to metal nanoparticles. Using new experimental methods, the two photon absorption and resulting UV emission from the nanoparticles are measured.

Physics is everywhere! – a journey from sub-atomic particles to the large-scale structure of the universe, where physics seeks to answer the most fundamental questions about reality. As we learn more, we can do more! Physics is everywhere in our world and underpins all our technologies. This year, Sean will discuss the important problems that all of us encounter every day: how do I teleport myself to school? What do I do when I find myself inside a black hole? Why is my time-machine not working? He will also talk about the superpowers that you can gain as a physicist, such as the ability to make accurate quantitative observations and predictive and interpretive mathematical models.  These powers mean that you can become very valuable and work in many industries such as fundamental physics research, economics and finance, space and aeronautics, healthcare and medicine, learning and teaching, electronics and computers, and so much more!

The John Mainstone Youth Lecture Tour 2018, Queensland

This year’s youth lecture tour will promote physics to senior high school students and science teachers. Commencing in August, Dr Sean Powell and Dr Jacqui Romero will present lectures in Physics to high school students in major centres across the state.

 

The 2018 AIP Lecture Series will be delivered by Dr Sean Powell.

 

Dr Powell’s talk in 2018 is titled Physics is everywhere! – a journey from sub-atomic particles to the large-scale structure of the universe, where physics seeks to answer the most fundamental questions about reality. As we learn more, we can do more! Physics is everywhere in our world and underpins all our technologies. This year, Sean will discuss the important problems that all of us encounter every day: how do I teleport myself to school? What do I do when I find myself inside a black hole? Why is my time-machine not working? He will also talk about the superpowers that you can gain as a physicist, such as the ability to make accurate quantitative observations and predictive and interpretive mathematical models.  These powers mean that you can become very valuable and work in many industries such as fundamental physics research, economics and finance, space and aeronautics, healthcare and medicine, learning and teaching, electronics and computers, and so much more!

 

An additional regional lecture will be delivered in Mount Isa in 2018 by Dr Jacqui Romero.

 

Dr Romero’s talk in 2018 will focus on Slower light in free space. The speed of light is nominally given by c/n, where n is the refractive index of the medium in which the light is travelling.  The refractive index of free space is 1, hence it is natural to expect that in free space, light travels at c. We show that this is not the case when you consider real beams.

We consider photons in a Bessel mode and a focused Gaussian mode, and show that in both cases, the reduction in group velocity results to a delay of several micrometers over a propagation distance of 1 m or ~30 femtoseconds in terms of arrival time.

Please refer to the attached itinerary for information regarding dates, times and venues and contact details for the host at each venue.

AIP 2018 Youth Lecture Itinerary Brief

There is no cost to attend these presentations; however, we do ask that you RSVP the organiser at each venue to indicate your school details, staff attending and anticipated student numbers , by Wednesday 25 July.

 

We would appreciate your assistance in forwarding this to any interested staff and students who may not receive it via the Physics Discussion list.

Meet the John Mainstone Youth Lecture Tour Speakers

The 2017 AIP Lecture Series will be delivered by Dr Helen Maynard-Casely.

 

Helen Maynard-Casely is a Planetary Scientist based at the Australian Nuclear Science and Technology Organisation (ANSTO) where she uses the neutrons and synchrotron x-rays to investigate the materials that make up our solar system.  She has a PhD in high-pressure physics from the University of Edinburgh and has been lucky enough to have collected data in facilities all over the world, blowing up a few diamonds along the way.  Always keen to tell anyone who’ll listen about planetary science, she writes a column ‘The Tides of Venus’ for The Conversation and tweets @Helen_E_MC.

Helen’s talk “Journeying to the centres of the planets” takes us on a journey, not just to visit the planets of our solar system, but to get to know them more intimately though understanding their varied and downright dangerous insides.  We’ve yet to actually dive under the clouds of the gas giants, crack through the ice of the dwarf planets or drill into the rocks of the terrestrial planets – so how do we know what lies beneath planetary surfaces?

An additional regional lecture will be delivered in Mount Isa in 2017 by Dr Sean Powell. Sean Powell’s research experience is in theoretical and computational modelling of particle dynamics and diffusion and MRI characterisation of diffusion in complex pore spaces. In addition, Sean has industry experience in computer software and hardware engineering, 3D visualisation systems, and solar thermal energy research. Presently, he leads the biofabrication research team within the Biofabrication and Tissue Morphology research group at the Queensland University of Technology. His quantitative and problem solving skills as a physicist complement those of the multi-disciplinary team of biologists, organic chemists, clinicians and medical engineers. He is also passionate about learning and teaching and lectures undergraduate physics at all year levels from introductory to advanced.
