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…
Cluster formation due to repulsive spanning trees in attractively coupled networks
Sayantan Nag Chowdhury, Md Sayeed Anwar, Dibakar Ghosh
Ensembles of coupled nonlinear oscillators are a popular paradigm and an ideal benchmark for analyzing complex collective behaviors. The onset of cluster synchronization is found t…
Interlayer antisynchronization in degree-biased duplex networks
Sayantan Nag Chowdhury, Sarbendu Rakshit, Chittaranjan Hens +1
With synchronization being one of nature's most ubiquitous collective behaviors, the field of network synchronization has experienced tremendous growth, leading to significant theo…
Effect of repulsive links on frustration in attractively coupled networks
Sayantan Nag Chowdhury, Dibakar Ghosh, Chittaranjan Hens
We investigate the impact of attractive-repulsive interaction in networks of limit-cycle oscillators. Mainly we focus on the design principle for generating an anti-phase state bet…
