    Dr. Matthias Ihl (University of Porto, Portugal)


    Good morning All,

    The National Institute for Theoretical Physics, and the Centre for Theoretical Physics, School of Physics, would like to invite to its coming talk in the theoretical physics seminar series, entitled:

    "Holographic zero sound at finite temperature in the Sakai-Sugimoto model"

    to be presented by Dr. Matthias Ihl (University of Porto, Portugal)

    Abstract: I will discuss the fate of the holographic zero sound mode at finite temperature and non-zero baryon density in the deconfined phase of the Sakai-Sugimoto model of holographic QCD and present our results forn the dispersion relation, quasi-normal modes, and spectral functions of the collective excitations in four different regimes, namely, the collisionless quantum, collisionless thermal, and two distinct hydrodynamic regimes. For sufficiently high temperatures, the zero sound completely disappears, and the low energy physics is dominated by an emergent diffusive mode. Finally, I compare our findings to Landau-Fermi liquid theory and to other holographic models.

    Dates: Tuesday, 25th November 2014 - TODAY
    Venue: P222 - DIFFERENT VENUE FOR TODAY
