PhD Submission - Muhammad Ahmed

After four years in the making Muhammad Ahmed has submitted his PhD thesis entitled "Confined magnon transport in low-dimensional ferromagnetic structures". In his thesis Muhammad has extensively investigated spin chains and 2D-arrays in the Heisenberg model and has developed methods to make use of spin exitations / magnons for classical and quantum information transport. He found ways to confine, accelerate and control the width of magnons in spin arrays as well as calculating a scheme to create and couple magnon guides and create a magnonic interferometer. During his PhD Muhammad also got married and his first child was born, two amazing life events which are certainly not made easier by PhD work. So congratulations on all your achievements in the last four years, Muhammad!

Success for NV laser magnetometry

This week we have two big steps forward for Prof. Greentree and Dr. Jan Jeske's Laser Threshold Magnetometry project. The first demonstration of stimulated emission from NV centres (arxiv.org/abs/1602.07418) has been accepted for publication and will appear in the next month or two. Secondly, Prof. Greentree has been awarded an Australian Research Council Future Fellowship in the most recent round for a project entitled - "Laser threshold sensing". This project aims to create a new class of room-temperature ultra-sensitive magnetometers based on laser threshold magnetometry. By using nitrogen-vacancy colour centres in diamond, these magnetometers will demonstrate at least femto-Tesla per root Hertz sensitivity, and could replace SQUID magnetometers. This project aims to develop its theoretical concept into a platform for advanced sensing with applications in magneto-encephalography, nerve sensing, MRI imaging, mining and aircraft guidance systems.

PhD Submission - Jackson Smith

Four years to the day (official SGR time) Jackson Smith has submitted his PhD thesis entitled "Modelling the electronic properties of zero-, one-, and two-dimensional phosphorus systems in semiconductors". Using a variety of theoretical techniques (both individually and in concert), Jackson studied electron transport in delta-doped phosphorous layers in silicon and germanium. In one thesis, Jackson developed a new method for treating two-dimensional delta-doped sheets using Thomas-Fermi theory, performed the first transport simulations of phosphorous nanowires, completed the largest DFT calculations this group has ever performed (in terms of number of atoms and memory) and computed the phosphorous donor energy level in silicon using ab-initio methods - finding an agreement with experiment of better than 10%. It also includes some of the most detailed appendices I've ever seen in a PhD thesis. This thesis is a testament to Jackson's breadth and depth of knowledge as a theorist as well as his dogged perfectionism. It is a most enjoyable read and I must admit, was well worth the wait. Excellent job Jackson.

ARC Centres of Excellence Announced

Today the Australian Research Council has announced the next round of funding for the ARC Centres of Excellence.

This is the ARC's flagship scheme for fundamental research, providing long term funding (7 years) for 15-20 Chief Investigators across several universities and other scientific organisations, both within Australia and overseas. TCQP is represented in two new Centres, the ARC Centre for Excellence in Exciton Science (Russo and Cole) and the ARC Centre for Excellence in Future Low Energy Electronics Technologies (Cole). This is in addition to our existing presence in the ARC Centre of Excellence for Nanoscale Biophotonics (Greentree).

Recent TCQP conferences, returning travellers and new results

TCQP had a good presence at two recent conferences. In February, Nicolas, Jackson and Jared all gave talks at ICONN 2016 in Canberra while in March Sam, David and Jared presented their work at the German Spring Meeting in Regensburg.

David Ing has finally returned from a 12 month exchange to the University of Ulm (Germany) and Sam has also returned from two months in the Karlsruhe Institute of Technology (Germany).

On the science front, Dr. Jan Jeske's work on lasing in the NV centre has had two recent successes with the publication of the original theoretical proposal (Jeske et al. Laser threshold magnetometry) as well as the first experimental measurements of Stimulated emission from NV centres in diamond. Speaking of the arXiv, Prof. Andrew Greentree has also recently posted a review of his favourite topic, Spatial adiabatic passage: a review of recent progress.
