Abstract
I will describe how effective actions featuring emergent degrees of freedom can be constructed by integrating over the UV part of the bulk geometry. This procedure allows to explain the presence of holographic gapless modes at zero temperature, reminiscent of zero sound in Fermi liquid and superfluid quantum sound. I will also describe ongoing work extending this construction for spacetimes with an infrared AdS_2xR^d geometry.
