abstract
We revisit a one-parameter family of three-dimensional gauge theories with known supergravity duals. We show that three infrared behaviors are possible. For generic values of the parameter, the theories exhibit a mass gap but no confinement, meaning no linear quark-antiquark potential; for one limiting value of the parameter the theory flows to an infrared fixed point; and for another limiting value it exhibits both a mass gap and confinement. Theories close to these limiting values exhibit quasi-conformal and quasi-confining dynamics, respectively. Eleven-dimensional supergravity provides a simple, geometric explanation of these features.

Dynamics of a Higgs phase transition in the Klebanov-Witten theory
In the holographic Klebanov-Witten plasma, D5-brane bubbles nucleate with a preferred flux that grows as 1/(T-Tc)^2, and their walls move at speeds below the conformal sound speed.
