The KABRU cluster will be mainly devoted to large scale numerical
simulations in the area of Lattice Gauge Theory. The main aim is to
understand the structure and properties of neutrons, protons, pions etc
from first principle simulations of the theory called Quantum
Chromodynamics (QCD). Despite the
best efforts for more than twenty years it has not been possible to do
reliable analytical calculations of these properties.
However, by exploiting the mathematical structure of Quantum Field
Theories(QFT) of which QCD is a particular realisation it is possible
to numerically simulate QCD on computers. This area of research has
become very active internationally. The NSAC Subcommittee of USA
has identified this area as No 1in importance for future research.
Even though the problems of QCD can be simulated on computers one
requires very fast supercomputers. Many of the forefront problems would
require 6 months to a year of running on Teraflop class supercomputers.
KABRU is a machine of that class.
Problems that will be immediately simulated on KABRU are as follows:
1. Very accurate studies of confinement properties and of the
QCD-string: this simulation is being carried out in collaboration with
Dr Pushan Majumdar who is currently at the University of Graz
as a Lise-Meitner fellow.
2. Studies of the equation of state and sound velocity in QCD at finite
temperature and density. This is being planned in collaboration with
Profs Sourendu Gupta and Rajiv Gavai of the ILGTI at TIFR.
