Toward Large N Thermal QCD from Dual Gravity: The Heavy Quarkonium Potential

Understand

We continue our study on the gravity duals for strongly coupled large N QCD with fundamental flavors both at zero and non-zero temperatures.

• The gravity dual at zero temperature captures the logarithmic runnings of the coupling constants at far IR and the almost conformal, albeit strongly coupled, behavior at the UV.
• The full UV completion of gauge theory is accomplished in the gravity side by attaching an AdS cap to the IR geometry described in our previous work.
• Attaching such an AdS cap is highly non-trivial because it amounts to finding the right interpolating geometry and sources that take us from a gravity solution with non-zero three-form fluxes to another one that has almost vanishing three-form fluxes.
