# Sound waves in strongly coupled non-conformal gauge theory plasma

@article{Benincasa2005SoundWI, title={Sound waves in strongly coupled non-conformal gauge theory plasma}, author={Paolo Benincasa and Alex Buchel and Andrei O. Starinets}, journal={Nuclear Physics}, year={2005}, volume={733}, pages={160-187} }

Using gauge theory/gravity duality we study sound wave propagation in strongly coupled non-conformal gauge theory plasma. We compute the speed of sound and the bulk viscosity of View the MathML source supersymmetric SU(Nc) Yang–Mills plasma at a temperature much larger than the mass scale of the theory in the limit of large Nc and large 't Hooft coupling. The speed of sound is computed both from the equation of state and the hydrodynamic pole in the stress–energy tensor two-point correlation…

Using the anti-de Sitter/conformal field theory correspondence, the shear viscosity eta of the finite-temperature N = 4 supersymmetric Yang-Mills theory is related with the absorption cross section of low-energy gravitons by a near-extremal black three-brane and it is shown that in the limit of zero frequency this cross section coincides with the area of the horizon.
