Aging in Citation Networks
Kamalika Basu Hajra, Parongama sen
In many growing networks, the age of the nodes plays an important role in deciding the attachment probability of the incoming nodes. For example, in a citation network, very old pa…
Phase Transitions in an Aging Network
Kamalika Basu Hajra, Parongama Sen
We consider a growing network in which an incoming node gets attached to the existing node with the probability , where is the degree of…
Is there a true Model-D critical dynamics?
Parongama Sen, Somendra M. Bhattacharjee
We show that non-locality in the conservation of both the order parameter and a noncritical density (model D dynamics) leads to new fixed points for critical dynamics. Depending up…
Short-time scaling in the critical dynamics of an antiferromagnetic Ising system with conserved magnetisation
Parongama Sen, Subinay Dasgupta
We study by Monte Carlo simulations the short-time exponent in an antiferromagnetic Ising system for which the magnetisation is conserved but the sublattice magnetisation (whic…
Coexistence of spanning clusters in directed percolation
Parongama Sen, Somendra M. Bhattacharjee
The probability distribution for the number of top to bottom spanning clusters in Directed percolation in two and three dimensions appears to be universal and is of the form $P(n)…
