The Origin of Dissipation in Quantum Many-Body Systems / V.Krivorol, M.Nalimov // 15th Chaotic Modeling and Simulation International Conference [Electronic resource] / Ed.: C.H.Skiadas, Y.Dimotikalis. – Cham : Springer, 2023. – P. 157-163. – URL: https://doi.org/10.1007/978-3-031-27082-6_13. – Bibliogr.: 13.

We discuss the dissipation phenomena and calculation of kinetic coefficients problem in quantum many-body systems. We consider the dynamics of equilibrium fluctuations in these systems and review the formalism of time dependent Green’s functions at finite temperature which is described in terms of Keldysh–Schwinger field theory. On the example of a non-relativistic Bose or Fermi system with weak local interaction we show how to define and calculate microscopic analogous of Onsager kinetic coefficients. We discuss the role of pinch singularities in problem of kinetic coefficients calculation. – (Springer Proceedings in Complexity) .
