Normally, a material’s decay rate reveals its underlying quantum structure, but in a novel topological superconductor, this connection fails. The Majorana rapidity matrix splits into independent sectors at zero chemical potential, yet local measurements detect only a combined decay rate, remaining oblivious to hidden topological states. This sector-blindness contrasts with other dissipative systems and unveils a more nuanced picture of non-Hermitian topology.
