Finite Temperature Holographic QCD via the Hard Wall Model

We study quark confinement and thermal deconfinement via holographic QCD. We use the hard wall model, where the AdS dual to the QCD is truncated, breaking the conformal symmetry in the IR regime. By studying the expectation value of the Wilson loop which is dual to the Nambu-Goto action in the bulk, we can extract the quark–anti-quark potential via gravity calculations at both zero and finite temperature
