Dense Holographic QCD in the Wigner-Seitz Approximation

Understand

We investigate cold dense matter in the context of Sakai and Sugimoto's holographic model of QCD in the Wigner-Seitz approximation.

• In bulk, baryons are treated as instantons on S^3\times R^1 in each Wigner-Seitz cell.
• In holographic QCD, Skyrmions are instanton holonomies along the conformal direction.
• The high density phase is identified with a crystal of holographic Skyrmions with restored chiral symmetry at about 4 Mkk^3/pi^5.
