For an even-length bosonic Kitaev chain, arbitrarily large loss on every other site leaves the zero-frequency topological amplification exactly unchanged, while odd-sized unit cells undergo a topological transition at a closed-form critical loss rate.

Topological Amplification of the Bosonic Kitaev Chain with Non-Uniform Loss
For an even-length bosonic Kitaev chain, arbitrarily large loss on every other site leaves the zero-frequency topological amplification exactly unchanged, while odd-sized unit cells undergo a topological transition at a closed-form critical loss rate.
