Quantum Regression theorem for multi-time correlators : A detailed analysis in the Heisenberg Picture
Sakil Khan, Bijay Kumar Agarwalla, Sachin Jain
Quantum regression theorem is a very useful result in open quantum system and extensively used for computing multi-point correlation functions. Traditionally it is derived for two-…
Constraining momentum space CFT correlators with consistent position space OPE limit and the collider bound
Sachin Jain, Renjan Rajan John, Abhishek Mehta +1
Consistency with position space OPE limit requires momentum space CFT correlators to have only total energy singularity. We show that this requirement gives a simple proof of the k…
Relation between parity-even and parity-odd CFT correlation functions in three dimensions
Sachin Jain, Renjan Rajan John
In this paper we relate the parity-odd part of two and three point correlation functions in theories with exactly conserved or weakly broken higher spin symmetries to the parity-ev…
Anyonic correlation functions in Chern-Simons matter theories
Yatharth Gandhi, Sachin Jain, Renjan Rajan John
Using a novel relation between the parity even and odd parts of a correlator, we show that the 3-point function of conserved or weakly broken currents in 3d CFT can be obtained fro…
Higher spin 3-point functions in 3d CFT using spinor-helicity variables
Sachin Jain, Renjan Rajan John, Abhishek Mehta +2
In this paper we use the spinor-helicity formalism to calculate 3-point functions involving scalar operators and spin- conserved currents in general 3d CFTs. In spinor-helicity…
Double copy structure of parity-violating CFT correlators
Sachin Jain, Renjan Rajan John, Abhishek Mehta +2
We show that general parity-violating 3d conformal field theories show a double copy structure for momentum space 3-point functions of conserved currents, stress tensor and margina…
