Self-amplifying synchronization in oscillator networks with state-dependent elastic coupling

Long-range synchronization of cardiomyocytes via purely elastic substrates is limited by the 1/r3 decay of mechanical interactions. Standard dipole models therefore predict only short-range phase coherence, leaving tissue-scale coordination unexplained. In this work, we introduce a state-dependent network model in which local phase coherence enhances contractile force through mechano-electric feedback. Numerical simulations on a 1D chain show that this feedback extends the spatial correlation le
