Conference paper

Evans TS, 1994, A New Time Contour for Thermal Field Theories, 3rd Workshop on Thermal Field Theories and their applications, Publisher: World Scientific, Pages: 77-82

A new time contour is used to derive real-time thermal field theory. Unlikeprevious path integral approaches, no contributions to the generatingfunctional are dropped.

Evans TS, 1991, N-Point Functions in Imaginary- and Real-Time at Finite Temperature, Amsterdam, 2nd Workshop on Thermal Field Theories and Their Applications, Publisher: North Holland, Pages: 441-447

It is proved that calculations of three-point diagrams using the Real-Time Formalism of finite temperature field theory produce the time-ordered Green functions while the Imaginary-Time Formalism calculate retarded and advanced Green functions. A non-trivial relation between these Green functions is found. Similarly, a spectral representation for the real-time three-point function is found. The high-temperature limit of one relation clarifies some of the problems found in the calculations of the running coupling constant of QCD at finite temperature.Some remarks on extending to N(>=4)-point functions will be made.

This is data used in the paper "Analysis of the Wikipedia Network of Mathematicians". The data is taken from three snapshots of Wikipedia, taken in 2013, 2017 and 2018. It contains the raw Wikipedia data used as our source as well the results of our processing. Includes are edgelists, networks of the largest comopnent in graphml format, and tables of data on the nodes (the mathematicians). We have also included an appendix for the EPJ version of the paper, mathematiciansEPJappendix.pdf. However a complete version of this work is also at arXiv:1902.07622

Working paper

Evans T, Imperial Workshop on Large Deviations Theory

Workshop on Large Deviations TheoryOn Wednesday 10th July 2013, a one day workshop on Large Deviations Theory was held at Imperial College London. It consisted of a series of invited talks by leading researchers and a session of very short talks. The aim was to connect researchers working on different aspects of Large Deviation Theory and those interested in applying these ideas. We covered a wide range of topics, trying to build capacity in this area within the UK. We covered both classical and quantum non-equilibrium systems, and applications both within physics and outside. All material related to this workshop, including some slides from the talks, are in this figshare collection.Funding was provided by the EPSRC NetworkPlus programme on Emergence and Physics far from Equilibrium.
