AUSTRALIAN INSTITUTE OF PHYSICS

Promoting the role of Physics in research, education, industry and the community

AIP LOGO

Theoretical Physics  Group (TPG)

The TPG in the AIP is focused on all areas of theoretical physics, from elementary particles in the quantum realm to the universe, and everything in between. Many, if not all, of these areas have an overlap with the other AIP topical groups. Purely theoretical studies in physics have lead to amazing technological changes in society, including computers and satellite communication.

Who Can Join the TPG?

Any members of the AIP who are interested in theoretical physics can join the TP Group as part of their AIP membership at no extra charge. To sign up to the TP Group, login to the Membership portal, then click on Theoretical Physics (TPG) under Topical Groups in your Membership Profile. Please take the time to do this as it gives the AIP a gauge of how much interest there is in TPG across Australia and beyond.

    The next AIP theoretical physics seminar speaker will be Susan Coppersmith (University of NSW) from 12noon AEST Thursday July 22.

    Abstract: Stochastic resonance, where noise synchronizes a system’s response to an external drive, is a phenomenon that occurs in a wide variety of noisy systems ranging from the dynamics of neurons to the periodicity of ice ages. This talk will present theory and experiments on a quantum system that exhibits stochastic resonance — the quantum tunneling of the magnetization of a single Fe atom measured using spin-polarized scanning tunneling microscopy. Stochastic resonance is shown deep in the quantum regime, where fluctuations are driven by tunneling of the magnetization, as well as in a semi-classical crossover region where thermal excitations set in. Combining theory and experiment enables one to probe the dynamics on time scales shorter than can be resolved experimentally.

    Abstract: After reviewing the basics of our current understanding of fundamental particles and their interactions, as enshrined in the Standard Model, Raymond Volkas briefly surveys the well-established evidence that this is an incomplete theory. The main part of the talk is then about recent measurements of the muon anomalous magnetic moment, and the rates of some B-meson decays, which point to possible further inadequacies of the Standard Model. Interestingly, the strongest current hints for this all involve muons.

    Abstract: The nature and origin of dark matter is one of the key unresolved questions of fundamental physics. Astrophysical and cosmological data provide powerful probes of dark matter properties, although to date no signal has been confirmed. In this webinar Tracy Slatyer discusses a number of claimed possible signals of novel dark matter physics in astrophysical datasets, alternative explanations, and open questions, with a focus on the Galactic Center Excess in GeV-scale gamma rays.
