  We discuss nuclear matter and the transition to quark matter in the
decompactified limit of the Sakai-Sugimoto model. Nuclear matter is included
through instantons on the flavor branes of the model. Our approximation is
based on the flat-space solution, but we allow for a dynamical instanton width
and deformation and compute the energetically preferred number of instanton
layers in the bulk as a function of the baryon chemical potential. We determine
the regions in parameter space where the binding energy of nuclear matter is
like in QCD, and compute the phase diagram in the plane of temperature and
chemical potential.
