DESCRIPTION:Title: <a href="https://researchseminars.org/talk/ATP2022/4/">
 Lecture: Schwinger-Keldysh formalism and open field theories</a>\nby Akhil
  Sivakumar (ICTS) as part of Advances in Theoretical Physics 2022\n\n\nAbs
 tract\nSchwinger-Keldysh path integral is a technique to study evolution o
 f mixed states. In this lecture\, I will introduce this formalism and expl
 ain how it can be used to compute the effective action of a quantum system
  interacting with a bath. Such a system will undergo non-unitary evolution
  and is an open quantum system. Using the toy model of a Brownian particle
 \, I will show how the data contained in the SK description can be mapped 
 to the more familiar form of a Langevin equation.\n
