Holographic Subregion Complexity in General Vaidya Geometry

Understand

We investigate general features of the evolution of holographic subregion complexity (HSC) on Vaidya-AdS metric with a general form.

• The spacetime is dual to a sudden quench process in quantum system and HSC is a measure of the ``difference'' between two mixed states.
• Based on the subregion CV (Complexity equals Volume) conjecture and in the large size limit, we extract out three distinct stages during the evolution of HSC: the stage of linear growth at the early time, the stage of linear growth with a slightly small rate during the intermediate time and the stage of linear decrease at the late time.
• The growth rates of the first two stages are compared with the Lloyd bound.
