Explosive phenomena in complex networks

RM D'Souza, J Gómez-Gardenes, J Nagler… - Advances in …, 2019 - Taylor & Francis
The emergence of large-scale connectivity and synchronization are crucial to the structure,
function and failure of many complex socio-technical networks. Thus, there is great interest …

Dimension reduction in higher-order contagious phenomena

S Ghosh, P Khanra, P Kundu, P Ji, D Ghosh… - … Journal of Nonlinear …, 2023 - pubs.aip.org
We investigate epidemic spreading in a deterministic susceptible-infected-susceptible
model on uncorrelated heterogeneous networks with higher-order interactions. We provide …

Double explosive transition in the synchronization of multilayer networks

T Wu, S Huo, K Alfaro-Bittner, S Boccaletti, Z Liu - Physical Review Research, 2022 - APS
We give evidence that consecutive explosive transitions may occur in two-layered networks,
when a dynamical layer made of an ensemble of networking phase oscillators interacts with …

Perfect synchronization in complex networks with higher-order interactions

S Dutta, P Kundu, P Khanra, C Hens, P Pal - Physical Review E, 2023 - APS
Achieving perfect synchronization in a complex network, specially in the presence of higher-
order interactions (HOIs) at a targeted point in the parameter space, is an interesting, yet …

Explosive synchronization: From synthetic to real-world networks

A Bayani, S Jafari, H Azarnoush - Chinese Physics B, 2022 - iopscience.iop.org
Synchronization is a widespread phenomenon in both synthetic and real-world networks.
This collective behavior of simple and complex systems has been attracting much research …

Extreme events in a complex network: Interplay between degree distribution and repulsive interaction

A Ray, T Bröhl, A Mishra, S Ghosh, D Ghosh… - … Journal of Nonlinear …, 2022 - pubs.aip.org
The role of topological heterogeneity in the origin of extreme events in a network is
investigated here. The dynamics of the oscillators associated with the nodes are assumed to …

Explosive synchronization in phase-frustrated multiplex networks

P Khanra, P Kundu, C Hens, P Pal - Physical Review E, 2018 - APS
We investigate the phenomenon of first-order transition [explosive synchronization (ES)] in
an adaptively coupled phase-frustrated bilayer multiplex network. We consider Sakaguchi …

Identifying symmetries and predicting cluster synchronization in complex networks

P Khanra, S Ghosh, K Alfaro-Bittner, P Kundu… - Chaos, Solitons & …, 2022 - Elsevier
Symmetries in a network connectivity regulate how the graph's functioning organizes into
clustered states. Classical methods for tracing the symmetry group of a network require very …

Explosive synchronization in multilayer networks through partial adaptation

P Khanra, P Pal - Chaos, Solitons & Fractals, 2021 - Elsevier
We propose an adaptive master-slave coupling scheme to achieve explosive
synchronization (ES) in a targeted (slave) layer of a multilayer network of Sakaguchi …

Predicting bursting in a complete graph of mixed population through reservoir computing

S Saha, A Mishra, S Ghosh, SK Dana, C Hens - Physical Review Research, 2020 - APS
