Derivation of fluctuating hydrodynamics and crossover from diffusive to anomalous transport in a hard-particle gas
Asaf Miron, Julien Cividini, Anupam Kundu +1
A recently developed non-linear fluctuating hydrodynamics theory has been quite successful in describing various features of anomalous energy transport. However the diffusion and t…
Driven tracer with absolute negative mobility
J. Cividini, D. Mukamel, H. A. Posch
Instances of negative mobility, where a system responds to a perturbation in a way opposite to naive expectation, have been studied theoretically and experimentally in numerous non…
Tagged particle in single-file diffusion with arbitrary initial conditions
Julien Cividini, Anupam Kundu
We compute the full probability distribution of the positions of a tagged particle exactly for given arbitrary initial positions of the particles and for general single-particle pr…
Zone clearance in an infinite TASEP with a step initial condition
Julien Cividini, Cécile Appert-Rolland
The TASEP is a paradigmatic model of out-of-equilibrium statistical physics, for which many quantities have been computed, either exactly or by approximate methods. In this work we…
Driven tracers in narrow channels
J. Cividini, D. Mukamel, H. A. Posch
Steady state properties of a driven tracer moving in a narrow two dimensional (2D) channel of quiescent medium are studied. The tracer drives the system out of equilibrium, perturb…
Exact correlations in a single file system with a driven tracer
A. Kundu, J. Cividini
We study the effect of a single driven tracer particle in a bath of other particles performing the random average process on an infinite line using a stochastic hydrodynamics appro…
Temperature profile and boundary conditions in an anomalous heat transport model
J. Cividini, A. Kundu, A. Miron +1
A framework for studying the effect of the coupling to the heat bath in models exhibiting anomalous heat conduction is described. The framework is applied to the harmonic chain wit…
Correlation and fluctuation in Random Average Process on an infinite line with a driven tracer
J. Cividini, A. Kundu, S. N. Majumdar +1
We study the effect of single biased tracer particle in a bath of other particles performing the random average process (RAP) on an infinite line. We focus on the large time behavi…
Exact gap statistics for the random average process on a ring with a tracer
Julien Cividini, Anupam Kundu, Satya N. Majumdar +1
We study statistics of the gaps in Random Average Process (RAP) on a ring with particles hopping symmetrically, except one tracer particle which could be driven. These particles ho…
Two dimensional outflows for cellular automata with shuffle updates
Chikashi Arita, Julien Cividini, Cécile Appert-Rolland
In this paper, we explore the two-dimensional behavior of cellular automata with shuffle updates. As a test case, we consider the evacuation of a square room by pedestrians modeled…
Stripe formation instability in crossing traffic flows
J. Cividini, H. J. Hilhorst
At the intersection of two unidirectional traffic flows a stripe formation instability is known to occur. In this paper we consider coupled time evolution equations for the densiti…
Crossing pedestrian traffic flows,diagonal stripe pattern, and chevron effect
J. Cividini, H. J. Hilhorst, C. Appert-Rolland
We study two perpendicular intersecting flows of pedestrians. The latter are represented either by moving hard core particles of two types, eastbound ($\symbp$) and northbound ($\s…
Continuous and first-order jamming transition in crossing pedestrian traffic flows
H. J. Hilhorst, J. Cividini, C. Appert-Rolland
After reviewing the main results obtained within a model for the intersection of two perpendicular flows of pedestrians, we present a new finding: the changeover of the jamming tra…
Diagonal patterns and chevron effect in intersecting traffic flows
Julien Cividini, Cecile Appert-Rolland, Hendrik-Jan Hilhorst
We study a lattice model of two perpendicular intersecting flows of pedestrians represented by hard core particles of two types, eastbound (`$\pE$') and northbound (`$\pN$'). Each…
Intersection of two TASEP traffic lanes with frozen shuffle update
C. Appert-Rolland, J. Cividini, H. J. Hilhorst
Motivated by interest in pedestrian traffic we study two lanes (one-dimensional lattices) of length that intersect at a single site. Each lane is modeled by a TASEP (Totally As…
Frozen shuffle update for an asymmetric exclusion process on a ring
C. Appert-Rolland, J. Cividini, H. J. Hilhorst
We introduce a new rule of motion for a totally asymmetric exclusion process (TASEP) representing pedestrian traffic on a lattice. Its characteristic feature is that the positions…
