## Abstract

In this talk I will describe numerical constructions of gravitational

duals of theories deformed by localized Dirac delta sources for scalar

operators. We perform two different constructions, one at zero and

the other at nonzero temperature. Surprisingly we find that imposing the preservation of scale

invariance at zero temperature requires the bulk scalar self-interaction potential to be

the one found in a certain Kaluza-Klein compactification of 11D supergravity.

The gravitational setup seems a-priori to be quite unusual and challenging

from the numerical relativity perspective.
