Dynamics of the entanglement rate in the presence of decoherence

The dynamics of the entanglement rate are investigated in this paper for pairwise interaction and two special sets of initial states. The results show that for the given interaction and the decoherence scheme, the competitions between decohering and entangling lead to two different results--some initial states may be used to prepare entanglement while the others do not. A criterion on decohering and entangling is also presented and discussed.Comment: 5 pages, 2 figure

'Exploring the bunker' - a response by Luke Bennett to 'Shallow Excavation'

This is a copy my response to Bradley L. Garrett's June 2011 critique of my paper in Environment & Planning D: Society and Space (2011) 29: 421-434 entitled 'Bunkerology - a case study in the theory and practice of urban exploration'. This response, and Garrett's critique are available at the EPD journal's webpage: www.societyandspace.com where free access to my original paper was also made available for a limited time
