Members of the Australian Institute of Physics, Queensland Branch.
You are invited to attend the upcoming Annual General Meeting.
The AGM will be held on the 15 November from 4pm – 5:30pm,
Room E207, E Block, Queensland University of Technology, Gardens Point Campus.
I am very pleased to announce that the QLD nominee for the 2019 Bragg Gold
Medal, Dr Satya Undurti, will be presenting his research prior to the AGM. More
information about his presentation are provided below.
The expected timing of the proceedings will be as follows:
4.00pm – 4.50pm Dr Satya Undurti presents his research
5.00pm – 5.30pm AGM
For catering purposes it would be appreciated if you could register your
attendance by Thursday the 14th of November
to aip_branchsecretary_qld@aip.org.au
. Catering will involve pizza and cold drinks.
We additionally hope to stream the presentation online using the Zoom platform. You can join us at AEST 4pm-5:30pm here.
Additionally, part of the business for the AGM will be to elect the branch
committee for 2020.
As per the AIP by-laws, the retiring committee has made nominations for next
year’s committee, and these are listed below:
Joel Alroe (Chair) (QUT),
Joanna Turner (Secretary) (USQ),
Scott Adamson (Vice-Chair) (All Hallows),
Igor Litvinyuk (Treasurer) (GU),
Carolyn Brown (USQ),
Scott Hoffman (post-graduate student representative UQ),
Austin Lund (UQ),
Nunzio Motta (QUT),
Till Weinhold (UQ)
Members may make further nominations, which need to be duly proposed and
seconded and forwarded to the Secretary at least 24 hours before the AGM,
directed to aip_branchsecretary_qld@aip.org.au
. I look forward to seeing you on 15th November!

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.
