Energy Momentum Tensor Correlators in Improved Holographic QCD
Martin Krssak
In this thesis, we study the physics of the quark gluon plasma (QGP) using holographic methods borrowed from string theory. We start our discussion by motivating the use of such ma…
Viscosity Correlators in Improved Holographic QCD
Martin Krssak
We study a bottom-up holographic model of large-Nc Yang-Mills theory, in which conformal invariance is broken through the introduction of a dilaton potential on the gravity side. W…
Energy momentum tensor correlators in hot Yang-Mills theory: holography confronts lattice and perturbation theory
K. Kajantie, Martin Krssak, Aleksi Vuorinen
We investigate the behavior of energy momentum tensor correlators in strongly coupled large-N_c Yang-Mills theory at nonzero temperature, working within the Improved Holographic QC…
Bulk and shear spectral functions in weakly and strongly coupled Yang-Mills theory
Aleksi Vuorinen, Martin Krssak, Yan Zhu
In this talk, we discuss a number of recent calculations aimed at determining the spectral functions corresponding to various components of the energy momentum tensor in high-tempe…
Frequency and wave number dependence of the shear correlator in strongly coupled hot Yang-Mills theory
K. Kajantie, Martin Krssak, M. Vepsalainen +1
We use AdS/QCD duality to compute the finite temperature Green's function G(omega,k;T) of the shear operator T_12 for all omega,k in hot Yang-Mills theory. The goal is to assess ho…
