From Modal Memory to Topological Relaxation in a Driven Holographic Superfluid

We study how driving history affects the nonlinear topological relaxation of a holographic superfluid. Different histories are constructed to reach the same present driving conditions and then follow the same future protocol. Although they relax to the same final winding sector, their late-time dynamics remain strongly history-dependent: the residence time of the penultimate winding sector changes by about a factor of $3.7$. This variation is organised by the modal imbalance carried into the common amplification stage. Histories with different shapes but matched modal imbalance produce nearly identical relaxation times. The same qualitative behaviour is found for a second pair of competing modes.
