We study the SakaiSugimoto model of holographic QCD at zero temperature and finite chemical potential. We find that as the baryon chemical potential is increased above a critical value, there is a phase transition to a nuclear matter phase characterized by a condensate of instantons on the probe Dbranes in the string theory dual. As a result of electrostatic interactions between the instantons, this condensate expands towards the UV when the chemical potential is increased, giving a holographic version of the expansion of the Fermi surface. We argue based on properties of instantons that the nuclear matter phase is necessarily inhomogeneous to arbitrarily high density. This suggests an explanation of the “chiral density wave ” instability of the quark Fermi surface in large Nc QCD at asymptotically large chemical potential. We study properties of the nuclear matter phase as a function of chemical potential beyond the transition and argue in particular that the model can be used to make a semiquantitative prediction of the binding energy per nucleon for nuclear matter in ordinary QCD. 1 Introduction and Summary
Light Nuclei as Quantized Skyrmions: Energy Spectra and Form Factors
, 2008
"... We review the SU(2) Skyrme model and describe its topological soliton solutions, which are called Skyrmions. Skyrmions provide a model of nuclei in which the conserved topological charge is identified with the baryon number of a nucleus. The semiclassical quantum theory of Skyrmions, in which they a ..."

We review the SU(2) Skyrme model and describe its topological soliton solutions, which are called Skyrmions. Skyrmions provide a model of nuclei in which the conserved topological charge is identified with the baryon number of a nucleus. The semiclassical quantum theory of Skyrmions, in which they are treated as rigid bodies spinning in space and isospace, is described. We derive the energy spectra corresponding to various light nuclei, and predict a few new states. We also calculate the electromagnetic form factors describing the structure of the αparticle and lithium6. Our recent reparametrization of the model gives results that are in reasonable quantitative agreement with experiment.

We review some recent progress in studying the nuclear physics especially nucleonnucleon (NN) force within the gaugegravity duality, in context of noncritical string theory. Our main focus is on the holographic QCD model based on the AdS 6 background. We explain the noncritical holography model and obtain the vectormeson spectrum and pion decay constant. Also, we study the NN interaction in this frame and calculate the nucleonmeson coupling constants. A further topic covered is a toy model for calculating the light nuclei potential. In particular, we calculate the light nuclei binding energies and also excited energies of some available excited states. We compare our results with the results of other nuclear models and also with the experimental data. Moreover, we describe some other issues which are studied using the gaugegravity duality.
