In-Medium Effects in the Holographic Quark-Gluon Plasma

Figure 21

A sketch of the positions and movements of the quasinormal frequencies under changes of 𝑑^𝐼̃‌. Color indicates the function: red=𝑌, green=𝑋, blue=𝐸³. The symbols indicate the range of 𝑑^𝐼̃‌: ∘<𝑑̃‌_crit, •=𝑑̃‌_crit, ▪>𝑑̃‌_crit. Poles in the gray region introduce instabilities.
