In-Medium Effects in the Holographic Quark-Gluon Plasma

Figure 13

A contour plot of the spectral function in the complex 𝔴-plane. Blue shading indicates ℜ>0, brown shading indicates ℜ<0. The gray contour traces ℜ=0. The values along the line Im𝔴=0 represent the physical spectrum we plotted for several parameters above.
