Complete Synchronization and its Transition in Higher Harmonic Sakaguchi--Kuramoto Oscillators
Subhasish Chowdhury, Sangita Dutta, Pitambar Khanra +2
In heterogeneous networks of coupled oscillators, phase frustration typically prevents the emergence of synchronization in the Sakaguchi--Kuramoto (SK) model. In this study, we pro…
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…
A double explosive Kuramoto transition in hypergraphs
Sangita Dutta, Prosenjit Kundu, Pitambar Khanra +4
This study aims to develop a generalised concept that will enable double explosive transitions in the forward and backward directions or a combination thereof. We found two essenti…
A Structural Feature-Based Approach for Comprehensive Graph Classification
Saiful Islam, Md. Nahid Hasan, Pitambar Khanra
The increasing prevalence of graph-structured data across various domains has intensified greater interest in graph classification tasks. While numerous sophisticated graph learnin…
Transition to synchronization in adaptive Sakaguchi-Kuramoto model with higher-order interactions
Sangita Dutta, Prosenjit Kundu, Pitambar Khanra +2
We investigate the phenomenon of transition to synchronization in Sakaguchi-Kuramoto model in the presence of higher-order interactions and global order parameter adaptation. The i…
State-transition dynamics of resting-state functional magnetic resonance imaging data: Model comparison and test-to-retest analysis
Saiful Islam, Pitambar Khanra, Johan Nakuci +3
Electroencephalogram (EEG) microstate analysis entails finding dynamics of quasi-stable and generally recurrent discrete states in multichannel EEG time series data and relating pr…
Impact of phase lag on synchronization in frustrated Kuramoto model with higher-order interactions
Sangita Dutta, Abhijit Mondal, Prosenjit Kundu +3
The study of first order transition (explosive synchronization) in an ensemble (network) of coupled oscillators has been the topic of paramount interest among the researchers for m…
Reliability of energy landscape analysis of resting-state functional MRI data
Pitambar Khanra, Johan Nakuci, Sarah Muldoon +2
Energy landscape analysis is a data-driven method to analyze multidimensional time series, including functional magnetic resonance imaging (fMRI) data. It has been shown to be a us…
Perfect synchronization in complex networks with higher order interactions
Sangita Dutta, Prosenjit Kundu, Pitambar Khanra +2
We propose a framework for achieving perfect synchronization in complex networks of Sakaguchi-Kuramoto oscillators in presence of higher order interactions (simplicial complexes) a…
Endowing networks with desired symmetries and modular behavior
P. Khanra, S. Ghosh, D. Aleja +7
Symmetries in a network regulate its organization into functional clustered states. Given a generic ensemble of nodes and a desirable cluster (or group of clusters), we exploit the…
Amplification of explosive width in complex networks
Pitambar Khanra, Prosenjit Kundu, Pinaki Pal +2
We present an adaptive coupling strategy to induce hysteresis/explosive synchronization (ES) in complex networks of phase oscillators Sakaguchi-Kuramoto model). The coupling strate…
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…
