Theory/Phenomenology Seminar
Holography and the Speed of Sound at High Temperature
Date: Friday, February 5th
Time: 2:30 pm - 3:30 pm
Place: 5280 Chamberlin Hall
Speaker: Paul Hohler, University of Illinois at Chicago
Abstract: An expression for the speed of sound will be formulated in a general class of strongly interacting theories using holographic techniques. Using this expression, it can be shown that for this class of theories at high temperatures the speed of sound approaches the conformal value cs2=1/3 universally from below. This class includes theories holographically dual to a theory of gravity coupled to a single scalar field, representing the operator of the scale anomaly.
