Chaos of interquark force via holography


  • Mr. Toshihiro OTA


AdS/CFT correspondence tells us that the energy of an open string hanging on the boundary of a curved spacetime is equivalent to the Wilson loop in the gauge theory side. In general, the motion of a string in a curved background shows chaotic behavior. Then, how is the chaos seen in observables in a QFT? We study the dynamics of an open string in the D4-soliton geometry which corresponds to a pure Yang-Mills theory and find it is chaotic. This means that the interquark force in 4d large Nc QCD is chaotic, and we evaluate the Lyapunov exponent.
