Normal modes and time evolution of a holographic superconductor after a quantum quench

Understand

We employ holographic techniques to investigate the dynamics of the order parameter of a strongly coupled superconductor after a perturbation that drives the system out of equilibrium.

• The gravity dual that we employ is the ${\rm AdS}_5$ Soliton background at zero temperature.
• We first analyze the normal modes associated to the superconducting order parameter which are purely real since the background has no horizon.
• We then study the full time evolution of the order parameter after a quench.
