Abstract
We investigate the effect of dissipation on the dynamics of edge modes in the monitored Su-Schrieffer-Heeger model. Our study considers both a linear observable and a nonlinear entanglement measure, namely the two-point correlation function and the disconnected entanglement entropy, as diagnostic tools. While dissipation inevitably alters the entanglement properties observed in the closed system, statistical analysis of quantum trajectories reveals that by protecting the chain's edges from dissipation, it is possible to recover characteristic features analogous to those found in the unitary limit. This highlights the fundamental role of spatial dissipation patterns in shaping the dynamics of edge modes in monitored systems.
