Description
Top-down realisations of gravitational systems holographically dual to
condensed matter systems have been usually constructed using consistent
Kaluza-Klein truncations associated to M2 or D3 branes in a planar
configuration. Here we will show that, associated to M5-branes wrapping
cycles of special holonomy manifolds, consistent truncations of D=11
supergravity also exist. We will discuss an specific example where the
truncated theory is D=4 N=2 matter-coupled supergravity and show that
this effective theory is amenable to further top-down AdS/CMT
investigations. In particular, by-passing previous no-go statements, we
are able to find a Lifshitz-invariant M-theory background.
