Fig. 4: The time evolution of the normalized spin textures with disorders in the phase modulator.
From: Topological holographic quench dynamics in a synthetic frequency dimension
The evolution of averaged spin polarization \(\overline {\langle {\sigma _y( {T,\tau })}\rangle }\), the overall spin polarization \(\overline {\langle {\sigma _y( \tau)}\rangle }\), the dynamical spin texture \(g_y(\tau )\), respectively, with parameters for Fig. 3a, b and disorder function \(f(t)\) in \(\kappa (t)\) and \(\kappa^{\prime}(t)\) with \(\delta = 10\%\) (a) and \(50\%\) (b), respectively. Black arrows point to values of \(g_y(\tau _{1,2})\)
