Current fluctuations in the Dyson Gas
Rahul Dandekar, P. L. Krapivsky, Kirone Mallick
We study large fluctuations of the current in a Dyson gas, a 1D system of particles interacting through a logarithmic potential and subjected to random noise. We adapt the macrosco…
Dynamic Space Packing
Rahul Dandekar, P. L. Krapivsky
Dynamic space packing (DSP) is a random process with sequential addition and removal of identical objects into space. In the lattice version, objects are particles occupying single…
Current fluctuations in an interacting active lattice gas
Stephy Jose, Rahul Dandekar, Kabir Ramola
We study the fluctuations of the integrated density current across the origin up to time in a lattice model of active particles with hard-core interactions. This model is amena…
Dynamical fluctuations in the Riesz gas
Rahul Dandekar, P. L. Krapivsky, Kirone Mallick
We consider an infinite system of particles on a line performing identical Brownian motions and interacting through the Riesz potential, causing the over-damped motion…
A Monte Carlo algorithm to measure probabilities of rare events in cluster-cluster aggregation
Rahul Dandekar, R. Rajesh, V. Subashri +1
We develop a biased Monte Carlo algorithm to measure probabilities of rare events in cluster-cluster aggregation for arbitrary collision kernels. Given a trajectory with a fixed nu…
Mass fluctuations in Random Average Transfer Process in open set-up
Rahul Dandekar, Anupam Kundu
We define a new mass transport model on a one-dimensional lattice of size with continuous masses at each site. The lattice is connected to mass reservoirs of different `chemica…
Macroscopic fluctuations of a driven tracer in the symmetric exclusion process
Rahul Dandekar, Kirone Mallick
The dynamics of an asymmetric tracer in the symmetric simple exclusion process (SEP) is mapped, in the continuous scaling limit, to the local current through the origin in the zero…
Transport and fluctuations in mass aggregation processes: mobility driven clustering
Subhadip Chakraborti, Tanmoy Chakraborty, Arghya Das +2
We calculate the bulk-diffusion coefficient and the conductivity in a broad class of conserved-mass aggregation processes on a ring of discrete sites. These processes involve chipp…
Hard core run and tumble particles on a one dimensional lattice
Rahul Dandekar, Subhadip Chakraborti, R. Rajesh
We study the large scale behavior of a collection of hard core run and tumble particles on a one dimensional lattice with periodic boundary conditions. Each particle has persistent…
Non Gaussian information of heterogeneity in Soft Matter
Rahul Dandekar, Soumyakanti Bose, Suman Dutta
Heterogeneity in dynamics in the form of non-Gaussian molecular displacement distributions appears ubiquitously in soft matter. We address the quantification of such heterogeneity…
Exact Hyperuniformity Exponents and Entropy Cusps in Models of Active-Absorbing Transition
Rahul Dandekar
Recent studies of nonequilibrium phase transitions have shown that in many systems which have transitions involving an arrested phase, the arrested states show suppressed density f…
A novel Recurrence-Transience transition and Tracy-Widom growth in a cellular automaton with quenched noise
Rahul Dandekar
We study the growing patterns formed by a deterministic cellular automaton, the rotor-router model, in the presence of quenched noise. By the detailed study of two cases, we show t…
Hierarchical Lattice Models of Hydrogen Bond Networks in Water
Rahul Dandekar, Ali A. Hassanali
We develop a graph-based model of the hydrogen bond network in water, with a view towards quantitatively modeling the molecular-level correlational structure of the network. The ne…
Logarithmic speed-up of relaxation in A-B annihilation with exclusion
Rahul Dandekar
We show that the decay of the density of active particles in the reaction in one dimension, with exclusion interaction, results in logarithmic corrections to th…
Comment on `Self-organized cooperative criticality in coupled complex systems'
Rahul Dandekar
In a recent Letter (EPL 105, 40006; arXiv:1309.7107), Liu and Hu presented a model of toppling-coupled sandpiles, where they found that the avalanche exponents for two toppling-cou…
Proportionate growth in patterns formed in the rotor-router model
Rahul Dandekar, Deepak Dhar
We study the growing patterns in the rotor-router model formed by adding walkers at the center of a two-dimensional square lattice, starting with a periodic backgr…
A class of exactly solved assisted hopping models of active-absorbing state transitions on a line
Rahul Dandekar, Deepak Dhar
We construct a class of assisted hopping models in one dimension in which a particle can move only if it does not lie in an otherwise empty interval of length greater than . W…
