Losing Forward Momentum Holographically

Understand

We present a numerical scheme for solving Einstein's Equations in the presence of a negative cosmological constant and an event horizon with planar topology.

• Our scheme allows for the introduction of a particular metric source at the conformal boundary.
• Such a spacetime has a dual holographic description in terms of a strongly interacting quantum field theory at nonzero temperature.
• By introducing a sinusoidal static metric source that breaks translation invariance, we study momentum relaxation in the field theory.
