2 p m Ioannis Papadimitriou (CERN) on "Holographic renormalization for generic Hamiltonian systems and application to Improved Holographic QCD" Where : 2nd floor seminar room Calendar: University of Crete HEP Seminars Description: ABSTRACT: Holographic renormalization has emerged as a systematic method for addressing certain pathologies, such as large distance divergences of the on-shell action and the ill-posedness of the variational problem, of supergravity in asymptotically anti de Sitter space in the context of the AdS/CFT correspondence. I will show that the same pathologies arise in a much wider class of Hamiltonian systems, not necessarily related with a holographic duality, and that the same techniques can be applied to these more general systems too. This opens the way for systematically understanding the holographic dictionary for many interesting holographic dualities involving non asymptotically AdS spaces. I will demonstrate this by carrying out the holographic renormalization program for the Improved Holographic QCD model of Gursoy and Kiritsis, which includes an asymptotically logarithmically running dilaton.
