| Outline of Final Research Achievements |
Based on the gauge-gravity correspondence predicted by the string theory, we can study the dynamics of field theories such as the quantum chromodynamics (QCD) in a simple way by mapping the problem to the classical gravity side via the correspondence. Using this technique, we studied various properties of dynamical phenomena in the field theory. In this project we tackled 1. chaos of the particle and string in AdS black hole spacetime, and 2. nonlinear effect in wave propagation and singularity formation. For the former, it turned out that chaotic behavior emerges due to the effect of the temperature of the system in the setup we focused on. For the latter, it was found that the singularity formation process such as the shock wave formation is suppressed in the models considered in the gauge-gravity correspondence, which implies that these models are healthy in the sense that they admit time evolution without singularity formation.
