Holography of the Quark Matter Triple Point

Understand

The quark matter phase diagram is believed to contain two distinguished points, lying on the boundary of the Quark-Gluon Plasma phase: a critical point and a triple point.

• In the holographic ["AdS/QCD"] approach, the region of relatively low chemical potentials around the phase transition near the critical point may be described using generalizations of the Hawking-Page transition.
• We propose that the \emph{other} QGP phase line, beginning at the triple point and rising towards the region of extremely high temperatures and chemical potentials, is described instead by a non-perturbative string effect discovered by Seiberg and Witten.
• Using an assumed position for the critical point, we are able to use this proposal to obtain a holographic lower bound on the temperature of the triple point.
