Query: Holographic stress tensor of colored Lifshitz spacetimes and hairy black
  holes   We compute the holographic stress tensor of colored Lifshitz spacetimes
following the proposal by Ross-Saremi for gravity duals of non-relativistic
theories. For a well-defined variational principle, we first construct a finite
on-shell action for the Einstein-Yang-Mills model in four dimensions with
Lifshitz spacetime as a solution. We then solve the linearised equations of
motion and identify the modes that preserve the asymptotically Lifshitz
condition. Employing these modes, we also show that the stress tensor is
finite, obeying the scaling and the diffeomorphism Ward identities, i.e.,
conservations laws. As a final application, we evaluate the energy density and
the spatial stress tensor of the previously found numerical black hole
solutions with various dynamical exponents $z$. The alternative Smarr relation
that has been used in Lifshitz black holes and the first law of thermodynamics
are shown to hold without a global Yang-Mills charge, indicating the black
holes in question are hairy.
