Universality of Resurgence in Quantization Theories

Asymptotic behaviour of the late-time expansion of Yang-Mills plasma

speaker: Ines Aniceto (Krakow University)

abstract: The non-equilibrium hydrodynamic phenomena in strongly coupled quantum systems such as the N= 4 supersymmetric Yang-Mills plasma, can be addressed with the tools of the AdSCFT correspondence, where calculations in the gravity side of the duality can be performed through a large proper-time expansion. This asymptotic expansion encodes a spectrum of non-hydrodynamic modes reflecting the frequencies of AdS black-brane quasinormal modes. The emerging structure for the description of physical quantities such as the energy density is of a resurgent transseries. It is also clear that one has to go beyond the linearized approximation leading to each quasinormal mode, and include sectors which can be thought of as involving nonlinear couplings between the different quasinormal modes. In this talk, I will present the calculation of the leading transseries sectors of the energy density of the Yang-Mills plasma through AdSCFT correspondence, and analyse its resurgent properties.
