Effect of initial conditions on current fluctuations in non-interacting active particles
Stephy Jose, Alberto Rosso, Kabir Ramola
We investigate the effect of initial conditions on the fluctuations of the integrated density current across the origin () up to a given time in a one-dimensional system o…
Fluctuation dominated phase ordering in coarse-grained depth models: Domain wall structures, extreme values and coarsening
Arghya Das, Mustansir Barma
Models of particles driven by a one-dimensional fluctuating surface are known to exhibit fluctuation dominated phase ordering (FDPO), in which both the order and fluctuations appea…
Coarsening, condensates and extremes in aggregation-fragmentation models
Chandrashekar Iyer, Arghya Das, Mustansir Barma
We use extreme value statistics to study the dynamics of coarsening in aggregation-fragmentation models which form condensates in the steady state. The dynamics is dominated by the…
Bias induced drift and trapping on random combs and the Bethe lattice: Fluctuation regime and first order phase transitions
Jesal D. Kotak, Mustansir Barma
We study the competition between field-induced transport and trapping in a disordered medium by studying biased random walks on random combs and the bond-diluted Bethe lattice abov…
Active Random Walks in One and Two Dimensions
Stephy Jose, Dipanjan Mandal, Mustansir Barma +1
We investigate active lattice walks: biased continuous time random walks which perform orientational diffusion between lattice directions in one and two spatial dimensions. We stud…
Phase transitions in XY models with randomly oriented crystal fields
Sumedha, M. Barma
We obtain a representation of the free energy of an XY model on a fully connected graph with spins subjected to a random crystal field of strength and with random orientation $…
