Condensed Matter

A fundamental open problem in condensed matter physics is how the dichotomy between conventional and topological band insulators is modified in the presence of strong electron interactions. In this talk I describe recent work showing that there are 6 new electronic topological insulators that have no non-interacting counterpart. Combined with the previously known band-insulators, these produce a total of 8 topologically distinct phases. Two of the new topological insulators have a simple physical description as Mott insulators in which the electron spins form spin analogs of the familiar topological band-insulator. The remaining are obtained as combinations of these two `topological paramagnets' and the topological band insulator. These 8 phases form a complete list of all possible interacting topological insulators, and are classified by a $\mathbb{Z}_2^3$ group-structure. As a necessary part of the talk I will also review progress in the theory of bosonic Symmetry Protected Topological phases in 3d.

3D Digital Holographic Interferometry: Applications in Biomedicine

August 16, 2013

PIRSA:13080047

Digital Holographic Interferometry (DHI) plays an important role in the evaluation of object static and dynamic displacements. The state of the art research on this technique is such that it is being used to solve problems in a wide variety of disciplines, from basic Physics to engineering and even social sciences. This invited plenary talk will deal with specific applications in some biomedical objects, even showing preliminary results using Electron Holography.
Atomic Physics in the Era of Control: What every physicist should know about the 2012 Physics Nobel Prize

To say that atomic, molecular, and optical (AMO) physics underwent a revival in the 80s and 90s is to acknowledge that it was in need of reviving. Prior to this rebirth, high-quality research was being done in many labs, but it was primarily passive with respect to atomic motion. The demonstration of laser cooling in 1978 ushered in a new era where the full quantum states (internal and external) of atoms would be precisely controlled in the following decades. This control has essentially given today’s AMO physicist the power to “realize the gedanken” and build experiments that exploit quantum mechanics to perform computations, simulations, and measurements with tremendous speed and precision. I will discuss some of the current challenges and potential of this exciting time in the field of AMO physics through the lens of a case study of some of the work of this year’s Nobel Laureates, Dave Wineland and Serge Haroche.

The impact of the Atmosphere on space-bound Vehicles

PIRSA:13080046

When rockets and space-bound vehicles are fired into space, they have to deal with turbulence, winds and waves in the Earth's atmosphere. Different height regimes cause different problems. In the lower regions (0 to 20 km altitude), winds and turbulence are major issues, whereas above 50 km altitude, large atmospheric waves have serious importance on safe passage. Similar issues arise on re-entry. In this talk, I will discuss the ways in which these atmospheric phenomena manifest themselves, and how they are best mitigated. One example of particular significance will be the Space Shuttle Columbia disaster, for which I consulted with NASA in respect to possible atmospheric influences. I will also describe some of the instrumentation used to measure these phenomena.
