Quark Matter and the 5th Dimension
Strongly-coupled quark matter takes on a variety of forms: bound states both familiar (protons, pions) and new (glueballs, pentaquarks), cold and dense neutron stars, and hot and dense quark-gluon plasma. Experiment and observation are providing more details of this quark matter phase diagram, but traditional theoretical techniques are incapable of handling the extreme strength of the forces involved. Recent theoretical developments from string theory have given us a surprising tool to study these strongly-coupled states. It has been suggested that weakly-coupled gravity with one extra dimension describes the same physics. Thermodynamic quantities can be explored by adding a black hole to the system. I will discuss the efforts within this model to describe two regimes of the phase diagram: 1. Cold and diffuse matter -- excited states of mesons and glueballs 2. Hot and dense matter -- thermodynamics of the quark-gluon plasma formed in heavy ion collisions and in the early universe
