About the collaboration
ILGTI is a loose collaboration of many Indian lattice gauge theorists who share resources and work. We are open to new members joining the collaboration. If you have a regular faculty position anywhere in India and would like to join the ILGTI, please contact us.
What we do
A short description
We are interested in the physics of matter in extreme conditions. An example of this is matter at temperatures in excess of 2 trillion degrees (2.1012 Kelvin or 175 MeV). Under such conditions matter takes extremely different forms and has peculiar properties. We compute the properties of such matter from a fundamental theory using supercomputers. Our computations are used in predicting results of experiments at CERN (Geneva) and BNL (New York). They also have implications for the evolution of the universe.
We are also interested in the structure and properties of composite particles which have strong interactions. In particular, we examine the properties of particles called glueballs, or particles with four or five quarks, or particles with heavy quarks. Collider experiments look for such exotic particles, and have already found a few.
One of our results
We performed measurements of quark number susceptibilties on the lattice. These measurements were made with a lattice spacing of a=1/(8T) where T is the temperature. Two flavours of staggered quarks were used, with the quark mass tuned so that mπ/mρ=0.33. At high temperature the results are close to what weak coupling theories predict. These results were reported in Lattice 2013. A table of our measurements is here.
We could certainly do with your help: whether you are a reasearch scientist, or a student. If you are a teacher and you would like to talk to us, we welcome contact. See our page on jobs, projects and contact for more details.
