Order parameter dynamics of the non-linear sigma model in the large N limit
Gemsheim, Sebastian; Mandal, Ipsita; Sengupta, Krishnendu; Wang, Zhiqiang (Peer reviewed; Journal article, 2020)We study non-equilibrium order parameter dynamics of the non-linear sigma model in the large N limit, using Keldysh formalism. We provide a scheme for obtaining stable numerical solution of the Keldysh saddle point equations ...
