An on-lattice model for two-dimensional melting
Antonin Rogé, Peter Holdsworth, Alexis Poncet
We introduce an on-lattice minimal model of two-dimensional melting, a clock model with vacancies with control parameters temperature, chemical potential and external field. We stu…
Full stochastic dynamics of a tracer in a dense single-file system
Alexis Poncet, Aurélien Grabsch, Olivier Bénichou
Tracer diffusion in single-file systems, where particles are restricted to move on a line without passing each other, has been a fertile ground to investigate anomalous diffusion a…
Exact spatial correlations in single-file diffusion
Aurélien Grabsch, Pierre Rizkallah, Alexis Poncet +2
Single-file diffusion refers to the motion of diffusive particles in narrow channels, so that they cannot bypass each other. This constraint leads to the subdiffusion of a tagged p…
Exact time dependence of the cumulants of a tracer position in a dense lattice gas
Alexis Poncet, Aurélien Grabsch, Olivier Bénichou +1
We develop a general method to calculate the exact time dependence of the cumulants of the position of a tracer particle in a dense lattice gas of hardcore particles. More precisel…
Exact closure and solution for spatial correlations in single-file diffusion
Aurélien Grabsch, Alexis Poncet, Pierre Rizkallah +2
Single-file transport, where particles diffuse in narrow channels while not overtaking each other, is a fundamental model for the tracer subdiffusion observed in confined systems,…
Generalised density profiles in single-file systems
Alexis Poncet, Aurélien Grabsch, Pierre Illien +1
Single-file diffusion refers to the motion in narrow channels of particles which cannot bypass each other. These strong correlations between particles lead to tracer subdiffusion,…
Cumulant generating functions of a tracer in quenched dense symmetric exclusion processes
Alexis Poncet, Olivier Bénichou, Pierre Illien
The Symmetric Exclusion Process (SEP), where particles hop on a 1D lattice with the restriction that there can only be one particle per site, is a paradigmatic model of interacting…
Pair correlation of dilute Active Brownian Particles: from low activity dipolar correction to high activity algebraic depletion wings
Alexis Poncet, Olivier Bénichou, Vincent Démery +1
We study the pair correlation of Active Brownian Particles at low density using numerical simulations and analytical calculations. We observe a winged pair correlation: while parti…
Bath-Mediated Interactions between Driven Tracers in Dense Single-Files
Alexis Poncet, Olivier Bénichou, Vincent Démery +1
Single-file transport, where particles cannot bypass each other, has been observed in various experimental setups. In such systems, the behaviour of a tracer particle (TP) is subdi…
-tag Probability Law of the Symmetric Exclusion Process
Alexis Poncet, Olivier Bénichou, Vincent Démery +1
The Symmetric Exclusion Process (SEP), in which particles hop symmetrically on a discrete line with hard-core constraints, is a paradigmatic model of subdiffusion in confined syste…
Unbinding transition of probes in single-file systems
Olivier Bénichou, Vincent Démery, Alexis Poncet
Single-file transport, arising in quasi one-dimensional geometries where particles cannot pass each other, is characterized by the anomalous dynamics of a probe, notably its respon…
Universal Long Ranged Correlations in Driven Binary Mixtures
Alexis Poncet, Olivier Bénichou, Vincent Démery +1
When two populations of "particles" move in opposite directions, like oppositely charged colloids under an electric field or intersecting flows of pedestrians, they can move collec…
