Effect of relative timescale on a system of particles sliding on a fluctuating energy landscape: Exact derivation of product measure condition
Chandradip Khamrai, Sakuntala Chatterjee
We consider a system of hardcore particles advected by a fluctuating potential energy landscape, whose dynamics is in turn affected by the particles. Earlier studies have shown tha…
Optimum transport in systems with time-dependent drive and short-ranged interactions
Deepsikha Das, Punyabrata Pradhan, Sakuntala Chatterjee
We study one-dimensional hardcore lattice gases, with nearest-neighbor interactions, in the presence of an external potential barrier, that moves on the periodic lattice with a con…
Dynamics of coupled modes for sliding particles on a fluctuating landscape
Shauri Chakraborty, Sakuntala Chatterjee, Mustansir Barma
The recently developed formalism of nonlinear fluctuating hydrodynamics (NLFH) has been instrumental in unraveling many new dynamical universality classes in coupled driven systems…
Current reversal in interacting colloids under time-periodic drive
Shubhashis Rana, Sanchari Goswami, Sakuntala Chatterjee +1
Using molecular dynamics simulations, we study particle-transport in a system of interacting colloidal particles on a ring, where the system is driven by a time-dependent external…
Ordered phases in coupled nonequilibrium systems: dynamic properties
Shauri Chakraborty, Sakuntala Chatterjee, Mustansir Barma
We study the dynamical properties of the ordered phases obtained in a coupled nonequilibrium system describing advection of two species of particles by a stochastically evolving la…
Ordered phases in coupled nonequilibrium systems: static properties
Shauri Chakraborty, Sakuntala Chatterjee, Mustansir Barma
We study a coupled driven system in which two species of particles are advected by a fluctuating potential energy landscape. While the particles follow the potential gradient, each…
Large compact clusters and fast dynamics in coupled nonequilibrium systems
Shauri Chakraborty, Sukla Pal, Sakuntala Chatterjee +1
We demonstrate particle clustering on macroscopic scales in a coupled nonequilibrium system where two species of particles are advected by a fluctuating landscape and modify the la…
Symmetric exclusion processes on a ring with moving defects
Rakesh Chatterjee, Sakuntala Chatterjee, Punyabrata Pradhan
We study symmetric simple exclusion processes (SSEP) on a ring in the presence of uniformly moving multiple defects or disorders - a generalization of the model proposed earlier [P…
Boundary induced phase transition with stochastic entrance and exit
Mithun Kumar Mitra, Sakuntala Chatterjee
We study an open-chain totally asymmetric exclusion process (TASEP) with stochastic gates present at the two boundaries. The gating dynamics has been modeled keeping the physical s…
Interacting particles in a periodically moving potential: Traveling wave and transport
Rakesh Chatterjee, Sakuntala Chatterjee, Punyabrata Pradhan +1
We study a system of interacting particles in a periodically moving external potential, within the simplest possible description of paradigmatic symmetric exclusion process on a ri…
Chemotaxis When Bacteria Remember: Drift versus Diffusion
Sakuntala Chatterjee, Rava Azeredo da Silveira, Yariv Kafri
{\sl Escherichia coli} ({\sl E. coli}) bacteria govern their trajectories by switching between running and tumbling modes as a function of the nutrient concentration they experienc…
Determinant representation for some transition probabilities in the TASEP with second class particles
Sakuntala Chatterjee, Gunter M. Schütz
We study the transition probabilities for the totally asymmetric simple exclusion process (TASEP) on the infinite integer lattice with a finite, but arbitrary number of first and s…
Importance of boundary effects in diffusion of hydrocarbon molecules in a one-dimensional zeolite channel
Sakuntala Chatterjee, Gunter M. Schütz
Single-file diffusion of propane and toluene molecules inside a narrow, effectively one-dimensional zeolite pore was experimentally studied by Czaplewski {\sl et al.} Using a stoch…
Diffusion of a hydrocarbon mixture in a one-dimensional zeolite channel: an exclusion model approach
Sakuntala Chatterjee, Gunter M. Schütz
Zeolite channels can be used as effective hydrocarbon traps. Earlier experiments (Czaplewski {\sl et al.}, 2002) show that the presence of large aromatic molecules (toluene) block…
Shock probes in a one-dimensional Katz-Lebowitz-Spohn model
Sakuntala Chatterjee, Mustansir Barma
We consider shock probes in a one-dimensional driven diffusive medium with nearest neighbor Ising interaction (KLS model). Earlier studies based on an approximate mapping of the pr…
Dynamics of Shock Probes in Driven Diffusive Systems
Sakuntala Chatterjee, Mustansir Barma
We study the dynamics of shock-tracking probe particles in driven diffusive systems and also in equilibrium systems. In a driven system, they induce a diverging timescale that mark…
Dynamics of Fluctuation Dominated Phase Ordering: Hard-core Passive Sliders on a Fluctuating Surface
Sakuntala Chatterjee, Mustansir Barma
We study the dynamics of a system of hard-core particles sliding downwards on a one dimensional fluctuating interface, which in a special case can be mapped to the problem of a pas…
