Gravity dual of N=4 SYM theory with fast moving sources

Understand

A family of wave solutions to the full Einstein equations in AdS_5 geometry is derived.

• These background solutions give by duality the response of N=4 SYM at strong coupling to an arbitrary distribution of fast moving external sources for the energy-momentum tensor operator.
• We discuss the similarities of these solutions with the Color Glass Condensate effective theory for QCD at high energy.
