Amin A. Nizami

Assistant Professor of Physics, Ashoka University

Ph.D. University of Cambridge

Amin received his PhD in Theoretical Physics from the Department of Applied Mathematics and Theoretical Physics, University of Cambridge. His research interests include various aspects of quantum field theory, holography and quantum information with the main area of specialisation being conformal field theory.

After obtaining his BSc in Physics (with Mathematics and Statistics) from AMU, Aligarh, India, he completed a Masters in Theoretical Physics from the University of Cambridge. Prior to joining Ashoka, he was a postdoctoral fellow at the International Centre for Theoretical Sciences (ICTS-TIFR).

An abiding research interest of mine has been Conformal Field Theory (CFT).  CFTs are special quantum field theories (QFTs) possessing scale invariance. They arise as fixed points of Renormalisation Group flow in the space of general QFTs. Because of the enhanced symmetries, and the existence of structures like the Operator Product Expansion, it  is possible to constrain/classify possible CFTs using consistency conditions such as crossing symmetry, unitarity and causality – this is the conformal bootstrap program. CFTs also find wide applicability in various areas of theoretical physics including cosmology, particle physics, holography, condensed matter and statistical physics. 

I have recently been working on momentum space correlators in 3d CFTs. I am also interested in exploring its connections to cosmological correlators.
