From local weight selection to Zeno slowdown in an open Su-Schrieffer-Heeger chain with a single local loss

arXiv:2607.10218v1 Announce Type: new Abstract: We study a quadratic open SSH chain with a single-site loss and show that the many-body fermionic Lindblad problem admits an exact reduction to a finite non-Hermitian one-body matrix with a rank-one imaginary impurity. Its rapidities generate the comp
