An abiding research interest of Amin 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.
He has recently been working on momentum space correlators in 3d CFTs. He is interested in exploring its connections to cosmological correlators.
