DESCRIPTION:Speakers: Kirill Boguslavski (University of Heidelberg)\n\nIn 
 the aftermath of heavy-ion collisions\, the formation of the quark-gluon p
 lasma is preceded by a short-lived\, highly energetic medium that evolves 
 toward hydrodynamization. Unequal-time correlation functions offer a power
 ful probe of the collective and transport properties of this QCD matter\, 
 as they encode its full excitation spectrum. In this talk\, I will discuss
  their implications for the applicability of kinetic theory and\, using th
 e heavy-quark diffusion coefficient as a case study\, for the microscopic 
 origin of transport properties relevant to hard probes. I will also addres
 s how such correlations can be computed beyond classical-statistical appro
 ximations in full quantum field theory. Recent progress in the real-time c
 omplex Langevin method has enabled the first ab-initio computation of uneq
 ual-time correlation functions in 3+1-dimensional Yang-Mills theory\, open
 ing a promising quantum route to studying the quark-gluon plasma.\n\nhttps
