Mean-Field and Pairwise Approaches for the SIRI Model on Poisson Networks
Akshara Bhat, Abhishek Deshpande, Chittaranjan Hens +1
Compartmental epidemic models, grounded in mass-action kinetics, often assume homogeneous mixing. Although this neglects network structure, recent results show that for Poisson ran…
Opinion-Driven Vaccination and Epidemic Dynamics on Heterogeneous Networks
Anika Roy, Ujjwal Shekhar, Subrata Ghosh +2
Vaccination campaigns play a pivotal role in controlling infectious diseases. Their success, however, depends not only on vaccine efficacy and availability but also significantly o…
Origins of Instability in Dynamical Systems on Undirected Networks
Shraosi Dawn, Subrata Ghosh, Chandrakala Meena +2
Robustness to perturbation is a key topic in the study of complex systems occurring across a wide variety of applications from epidemiology to biochemistry. Here we analyze the eig…
Real-time identification and control of influential pandemic regions using graph signal variation
Sudeepini Darapu, Subrata Ghosh, Dibakar Ghosh +2
The global spread of pandemics is facilitated by the mobility of populations, transforming localized infections into widespread phenomena. To contain it, timely identification of i…
Predicting First-Passage Dynamics in Disordered Systems Exactly: Application to Sparse Networks
Daniel Marris, Chittaranjan Hens, Subrata Ghosh +1
Quantifying how spatial disorder affects the movement of a diffusing particle or agent is fundamental to target search studies. When diffusion occurs on a network, that is on a hig…
Teleportation Fidelity of Binary Tree Quantum Repeater Networks
Soumit Roy, Md Rahil Miraj, Chittaranjan Hens +3
Binary tree network, being a subclass of Cayley tree network, is a significant topological structure used for information transfer in a hierarchical sense. In this article, we cons…
Enhancing cluster synchronization in phase-lagged multilayer networks
Abhijit Mondal, Pitambar Khanra, Subrata Ghosh +3
Cluster synchronization in multilayer networks of phase oscillators with phase-lag poses significant challenges due to the destabilizing effects of delayed interactions. Leveraging…
Teleportation fidelity of quantum repeater networks
Ganesh Mylavarapu, Subrata Ghosh, Chittaranjan Hens +2
We show that the average of the maximum teleportation fidelities between all pairs of nodes in a large quantum repeater network is a measure of the resourcefulness of the network a…
Impact of Diffusion on synchronization pattern of epidemics in nonidentical metapopulation networks
Anika Roy, Ujjwal Shekhar, Aditi Bose +4
In a prior study, a novel deterministic compartmental model known as the SEIHRK model was introduced, shedding light on the pivotal role of test kits as an intervention strategy fo…
Higher order interactions in Kuramoto oscillators with inertia
Patrycja Jaros, Subrata Ghosh, Dawid Dudkowski +2
How higher-order interactions influence the dynamics of second order phase oscillators? We address this question using three coupled Kuramoto phase oscillators with inertia under b…
Extreme events in a complex network: interplay between degree distribution and repulsive interaction
Arnob Ray, Timo Bröhl, Arindam Mishra +5
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 be…
Identifying Influential Pandemic Regions Using Graph Signal Variation
Sudeepini Darapu, Subrata Ghosh, Abhishek Senapati +2
Developing methods to analyse infection spread is an important step in the study of pandemic and containing them. The principal mode for geographical spreading of pandemics is the…
Identifying symmetries and predicting cluster synchronization in complex networks
Pitambar Khanra, Subrata Ghosh, Karin Alfaro-Bittner +4
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 ver…
