Non-Hermitian route to higher-order topology in an acoustic crystal

Losses, due to their non-Hermitian nature, are generally disregarded or even considered harmful when looking for non-trivial topological phases. Here, the authors experimentally demonstrate that higher-order topology can emerge as a result of introducing losses in an acoustic crystal.
