Explosive Synchronization in Complex Network Zahra Ghahreman z ghahreman@ph iut ac ir Department of Physics Isfahan University of Technology Isfahan 84156 83111 IranDegree M Sc Language PersianSupervisor Dr Keivan Aghababaei Samani samani@cc iut ac irAbstractAlready some information about synchronization kuramoto model structure of networks and somespecial property of networks was submitted In this study we focus on explosive synchronization transition If we assume a set of networks withequal average of degrees then correlate dynamical and structural attributes i e identify the internalfrequency of each node directly with it s degree explosive synchronization will be observed in scalefree networks In this algorithm we have all nodes and select one of them and draw it s edges with uniform orpreferential probability that is an arbitrary parameter between 0 and 1 Replacing a positive exponentof their degree with internal frequency repeat the transition too Recently scientists use mean fieldapproximations to determine the critical coupling of such explosive synchronization The results showan inverse dependence with the network average of degrees Now we change previous algorithm andmake network growing with time i e a node will added at each step of time and its edges will drewwith same arbitrary parameter named So we can see explosive synchronization at 3 values of The transition didn t seen for randomgraph Also we qualify some properties of two networks and compare them to realize the reasons oftheir variances Keywords Synchronization Network Kuramoto model Explosive transition
