Theoretical High Energy Physics (HEP-TH) deals with developing theoretical and mathematical frameworks needed in physical model building, especially in particle physics and cosmology areas, and/or addressing the issues and shortcomings of the existing frameworks. Currently, Einstein's General Relativity  (GR) and Quantum Field Theory (QFT) constitute the foundations upon which our particle physics and cosmology are built. Solutions to GR are typically singular (like black holes and in Big Bang cosmology), and our knowledge of QFT is generically limited to the weakly coupled regime where perturbation theory is applicable. Moreover, there are regimes of physical interest where Quantum Theory and GR should be put together, like questions regarding the physics of black holes  (BHs) and around the Big Bang.

HEP-TH & GR-QC group of the IPM school of theoretical physics are exploring further development of existing frameworks to address the questions in GR and/or QFT, as well as studying GW and their detection potentials. In particular, we are exploring questions regarding the basic structure of spacetime, physics of black holes, and aspects of AdS/CFT duality, and the nature of gravity itself.
