String Theory and Quantum Gravity

Unification of  General Relativity and Quantum Mechanics into a  coherent theory of Quantum Gravity has been one of the outstanding challenges in theoretical physics.  Such a framework is…

String Theory and Quantum Gravity
Phenomenology of Particle Physics

Researchers in this area, which bridges theoretical physics (such as quantum field theory and theories of the structure of spacetime) and experimental particle physics, are exploring: beyond the…

Phenomenology of Particle Physics
Cosmology

The study of the large-scale structure and the evolution of the universe has in the last few years entered a qualitatively new phase, driven by a host of experimental results. Topics being studied…
