Summary

 

Summary

I am currently a member of the Theoretical Physics Group and, in addition, a member of the cross-disciplinary Centre for Complexity Science, My current research follows two broad, but very different, paths that reflect this duality: quantum field theory and complex spatial networks.

For the former I have interests in Fermi gas condensates with the National Dong Hwa University in Taiwan, in Casimir effects with APC, U. of Paris 7, with Josephson Tunnel Junctions at DTU Lyngby and with non-standard entropies at the Technical University of Prague.

My work on complexity, which is currently my major activity, is largely in collaboration with Tim Evans of the Theoretical Physics Group and students at the Centre for Complexity Science and addresses applications and issues in modelling archaeological networks. In this I am part of a mainly European grouping incorporating computer scientists and archaeologists (in particular, at this moment, ETH Zurich, U. of Cologne, U. of Kiel, U. of Toronto). Such modelling is strongly influenced by that used in contemporary urban planning for transport, commuting and city development and by ecologists for characterising assemblages. Like astrophysics, archaeology is intrinsically Bayesian although data is very poor but an information-theoretic approach e.g. MaxEnt, is very productive. I have been particularly concerned with the limitations of modelling e.g. the role of contingency. 

Whereas quantum field theory papers can be found easily on the arXiv, in archaeology our/my papers infrequently in journals (e.g. Antiquity) but usually in monographs (sometimes published years after the event). Tim Evans' web page gives access to some of them.
