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
Dr. Nathan Broomhead recently presented his latest research at the Nankai Symposium on Physics, Geometry and Number Theory 2017 in China.
The Chern Insitute is a legacy of Prof. S-S Chern who had the vision of having a symposium at his Alma Mater of Nankai University in the direction of the dialogue between modern mathematics and theoretical physics.
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.
In the Cube3 gallery space in the Portland Square Building on the campus, there are two portraits of Professor David McMullan (Associate Head of School ) and Dr. David Wilton (former head of Mathematics). Dr. Wilton is currently chair of the Plymouth Astronomical Society.
The pictures were painted by the local artist Jo beer. There is more information about the exhibition here.
This week the center for mathematical sciences has hosted a student from Callington Community College, who is studying for GSCEs, for work experience. The student was interested in learning more about quantum mechanics. The list of his activities is here.
The ultimate goal was to learn enough physics to work with IBM’s quantum computer in the cloud.
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.
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
A student from Plymouth High School for Girls has been working with Julian Stander and Luciana Dalla Valle on developing an R software graphical tool to display data for the twenty geographical regions of Italy.
This tool has been used to understand how variables such as population structure and GDP per Capita have changed over time in each region.
The following article was orginally circulated in the staff bulletin.
Two Theoretical Physics Lecturers have just returned from China after sharing their research with a number of high-profile organisations. Dr Ben King gave lectures on strong field physics at the National University of Defence Technology (NUDT) summer school in Changsha, and was also invited to collaborate with researchers at the China Aerodynamics Research and Development Centre (CARDC), where he spent one month working on quantum electrodynamics in intense fields. Meanwhile, Dr Tom Heinzl went to Shanghai to present his research and sit on the committee of an International Review Meeting thanks to sponsorship from the Shanghai Institute of Optics and Fine Mechanics (SIOM) and the Chinese Academy of Sciences. The meeting’s purpose was to discuss and review the scientific opportunities for the ‘Station of Extreme Light’ (SEL) at the Shanghai Coherent Light Facility (SCLF), and explore the conceptual design and technical approach towards a 100-petawatt laser.
This month Dr. Matthew Craven is talking at the Genetic and Evolutionary Computation Conference (GECCO 2017) in Berlin.
The titles of Matthew’s talks are below
- Exploring the (Efficient) Frontiers of Portfolio Optimization
Matthew J. Craven, David I. Graham
- BBIOS: A Characterization of Evolutionary Algorithm Stability
Matthew J. Craven, Simon P. Martin
