SUMMARY:Holography and the Speed of Sound at High Temperature\, Theory
 /Phenomenology Seminar\, Paul Hohler\, University of Illinois at Chica
 go
DESCRIPTION:An expression for the speed of sound will be formulated in
  a general class of strongly interacting theories using holographic te
 chniques. Using this expression\, it can be shown that for this class 
 of theories at high temperatures the speed of sound approaches the con
 formal value cs2=1/3 universally from below. This class includes theor
 ies holographically dual to a theory of gravity coupled to a single sc
 alar field\, representing the operator of the scale anomaly.<br>
