Cost-benefit analysis of Australian Federal Police counter-terrorism operations at Australian airports

The terrorist attacks of 11 September 2001 highlighted the vulnerabilities of airports and aircraft. Further attacks in 2002, 2007 and 2009, have led to major government reforms in passenger processing and airport access. The security of Australian airports has also followed this trend, with an increased police presence. However, limited consideration has been given to the costs of these measures, compared to benefit. This Working Paper identifies the factors to be considered in such cost-benefit analyses and the authors outline their preliminary findings. The scope for further research is highlighted, particularly in relation to risk analysis and cost

Notes from the 3rd Axion Strategy Meeting

In this note we briefly summarize the main future targets and strategies for axion and general low energy particle physics identified in the "3rd axion strategy meeting" held during the AXIONS 2010 workshop. This summary follows a wide discussion with contributions from many of the workshop attendees.Comment: 5 pages, 1 figur

Even-Odd Correlation Functions on an Optical Lattice

We study how different many body states appear in a quantum gas microscope, such as the one developed at Harvard [Bakr et al. Nature 462, 74 (2009)], where the site-resolved parity of the atom number is imaged. We calculate the spatial correlations of the microscope images, corresponding to the correlation function of the parity of the number of atoms at each site. We produce analytic results for a number of well-known models: noninteracting bosons, the large U Bose-Hubbard model, and noninteracting fermions. We find that these parity correlations tend to be less strong than density-density correlations, but they carry similar information.Comment: 8 pages, 4 figures. Published versio
