Small-world properties of the Indian Railway network
Parongama Sen, Subinay Dasgupta, Arnab Chatterjee +3
Structural properties of the Indian Railway network is studied in the light of recent investigations of the scaling properties of different complex networks. Stations are considere…
Phase transitions in a network with range dependent connection probability
Parongama Sen, Kinjal Banerjee, Turbasu Biswas
We consider a one-dimensional network in which the nodes at Euclidean distance can have long range connections with a probabilty in addition to nearest neigh…
Persistence in an antiferromagnetic Ising model with conserved magnetisation
Moumita Saharay, Parongama Sen
We obtain the persistence exponents for an antiferromagnetic Ising system in which the magnetisation is kept constant. This system belongs to Model C (system with non-conserved ord…
Modulated Scale-free Network in the Euclidean Space
S. S. Manna, Parongama Sen
A random network is grown by introducing at unit rate randomly selected nodes on the Euclidean space. A node is randomly connected to its -th predecessor of degree with a…
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…
