Gravity dual of a multilayer system

Understand

We construct a gravity dual to a system with multiple (2+1)-dimensional layers in a (3+1)-dimensional ambient theory.

• Following a top-down approach, we generate a geometry corresponding to the intersection of D3- and D5-branes along 2+1 dimensions.
• The D5-branes create a codimension one defect in the worldvolume of the D3-branes and are homogeneously distributed along the directions orthogonal to the defect.
• We solve the fully backreacted ten-dimensional supergravity equations of motion with smeared D5-brane sources.
