DESCRIPTION:Title: <a href="https://researchseminars.org/talk/ATP2022/9/">
 Quantum Perturbiner Method</a>\nby Kanghoon Lee (APCTP) as part of Advance
 s in Theoretical Physics 2022\n\n\nAbstract\nWe construct the off-shell re
 cursion relation for arbitrary loop-level scattering amplitudes beyond the
  tree-level Berends-Giele recursion relation for any quantum field theory.
  We define the quantum perturbiner expansion from the quantum effective ac
 tion formalism\, including the perturbative quantum corrections. Instead o
 f the classical EoM in the conventional perturbiner method\, we exploit th
 e Dyson-Schwinger equation to derive the recursion relation for arbitrary 
 order of loop-level scattering amplitudes. Furthermore\, we extend this te
 chnique to compute the loop-level correlation functions.\n
