  We study cold and dense nuclear matter by using the gauge/gravity duality. To
this end we use the Witten-Sakai-Sugimoto model and the V-QCD models with an
approach where the nuclear matter is taken to be spatially homogeneous. We
focus on the ''popcorn'' transitions, which are phase transitions in the
nuclear matter phases induced by changes in the layer structure of the
configuration on the gravity side. We demonstrate that the equation of state
for the homogeneous nuclear matter becomes approximately conformal at high
densities, and compare our results to other approaches.
