Dirac day in Exeter

The people in the center of Mathematical Sciences at Plymouth University, who do research into lattice gauge theory, make extensive use of the high performance computers in Dirac (Distributed Research utilising Advanced Computing). DiRAC is the UK’s HPC facility for astrophysics, cosmology, nuclear physics and particle physics

Every year researchers, who use the resources from Dirac, come together for a one day meeting (called Dirac Day) to share research results and experiences. This year Dirac Day is in Exeter.

Craig McNeile is presenting a poster with the title:

Using parallel eigensolvers in lattice QCD calculations


Award for best paper in international journal

The article below was circulated on the Staff bulletin.

Dr Ben King and Dr Tom Heinzl, both Lecturers in Theoretical Physics, have received the 2016 Editor-in-Chief Choice Award from the journal High Power Laser Science and Engineering (HPL). Their paper Measuring vacuum polarization with high-power lasers (doi: 10.1017/hpl.2016.1) was commended for delivering ‘new and important results’, and the pair have been invited to collect the award and give a talk on their research at the 3rd International Symposium on High Power Laser Science and Engineering in Suzhou, China next year.


Sabbatical at CERN

The staff in the mathematical sciences at Plymouth University have a number of different components to their job descriptions. It is obviously important to be an excellent teacher, but another part of the job description is maintaining  international leadership in a research field. There are other hidden part of the job too , such as administration.

If external support can be found, staff can take a sabbatical, typically for a year,  at another institution, so that can concentrate on their research. Dr. Antonio Rago from CMS is visiting CERN for the year 2017-2018 to work on research full time. He is working in the theory division of CERN.

Talk in Israel

Dr. Daniel Robertz from CMS is presenting a talk at the 23rd Conference on Applications of Computer Algebra  in Jerusalem. The title of the talk is: Towards a symbolic package for systems of nonlinear difference equations.


Difference algebra has been studied in analogy to differential algebra. However, concepts such as characteristic sets for differential systems have not been developed in the same generality for difference systems yet. In particular, methods such as the Rosenfeld-Gröbner algorithm, regular chains and Thomas decomposition for differential systems are not  available for difference systems. Among the
many applications of difference algebra is, e.g., the consistency analysis of finite difference schemes for partial differential equations.
This talk presents results of trying to transfer the concept of differential Thomas decomposition to systems of nonlinear difference equations and develop a symbolic package for systems of nonlinear difference equations. It reports on joint work with Vladimir Gerdt
