Topological phases in phononic systems enable robust and unconventional control of wave propagation. However, realistic acoustic, elastic, and mechanical platforms are open, while loss or gain, active feedback, and spatiotemporal modulation provide tunable routes to non-hermiticity and nonreciprocity. Non-hermiticity r...
