Instanton dynamics in finite temperature QCD via holography

Understand

We investigate instantons in finite temperature QCD via Witten's holographic QCD.

• To study the deconfinement phase, we use the setup proposed in [1] (arXiv:1107.4048).
• We find that the sizes of the instantons are stabilized at certain values both in the confinement and deconfinement phases.
• This agrees with the numerical result in the lattice gauge theory.
