Dynamics of unvisited sites in presence of mutually repulsive random walkers
Pratap K. Das, Subinay Dasgupta, Parongama Sen
We have considered the persistence of unvisited sites of a lattice, i.e., the probability that a site remains unvisited till time in presence of mutually repulsive rando…
Modelling temporal and spatial features of collaboration network
Anjan Kumar Chandra, Kamalika Basu Hajra, Pratap Kumar Das +1
The collaboration network is an example of a social network which has both non-trivial temporal and spatial dependence. Based on the observations of collaborations in Physical Revi…
Time evolution of link length distribution in PRL collaboration network
Parongama Sen, Anjan Kumar Chandra, Kamalika Basu Hajra +1
An important aspect of a Euclidean network is its link length distribution, studied in a few real networks so far. We compute the distribution of the link lengths between collabora…
Dynamical frustration in ANNNI model and annealing
Parongama Sen, Pratap Kumar Das
Zero temperature quench in the Axial Next Nearest Neighbour Ising (ANNNI) model fails to bring it to its ground state for a certain range of values of the frustration parameter …
Zero temperature dynamics of Ising model on a densely connected small world network
Pratap Kumar Das, Parongama Sen
The zero temperature quenching dynamics of the ferromagnetic Ising model on a densely connected small world network is studied where long range bonds are added randomly with a fini…
Probability distribution of persistent spins in a Ising chain
Pratap Kumar Das, Parongama Sen
We study the probability distribution of , the fraction of spins unflipped till time , in a Ising chain with ferromagnetic interactions. The distribution shows a…
