How Mobile Oscillators Reshape Dynamical Robustness in Complex Networks
Sayantan Nag Chowdhury, Srilena Kundu
While the robustness of collective dynamics in static networks is well established, how agent mobility and network topology jointly shape dynamical robustness remains largely unexp…
Periodic Environmental Forcing Shapes the Stability of Complex Ecological Networks
Sayantan Nag Chowdhury
Environmental variability is a defining feature of natural ecosystems, yet many theories of ecological stability assume static environments. Here, we develop an analytical framewor…
Metastability induced by non-reciprocal adaptive couplings in Kuramoto models
Sayantan Nag Chowdhury, Hildegard Meyer-Ortmanns
Non-reciprocal couplings are frequently found in systems out-of-equilibrium such as neuronal networks. We consider generalized Kuramoto models with non-reciprocal adaptive coupling…
Topologically protected edge oscillations in nonlinear dynamical units
Sayantan Nag Chowdhury, Hildegard Meyer-Ortmanns
Many examples from quantum and classical physics are known where topological protection is responsible for the robustness of the dynamics. Less explored is the role of topological…
How Combined Pairwise and Higher-Order Interactions Shape Transient Dynamics
Sourin Chatterjee, Sayantan Nag Chowdhury
Understanding how species interactions shape biodiversity is a core challenge in ecology. While much focus has been on long-term stability, there is rising interest in transient dy…
Cluster formation due to repulsive spanning trees in attractively coupled networks
