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…
Phase coherence and disorder-induced wave propagation in micromotor arrays
Romane Braun, Alexis Poncet, Alexandre Morin +1
Machines are designed, assembled, and programmed to convert power into predetermined dynamics and functions. In contrast, living systems such as interacting cells and animal groups…
Learning general pair interactions between self-propelled particles
Jérôme Hem, Alexis Poncet, Pierre Ronceray +2
Synthetic active matter systems, such as active colloids, often have complex interactions, which can be of hydrodynamic, chemical or electrostatic origin and cannot be computed fro…
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…
Melting of non reciprocal solids: how dislocations propel and fission in flowing crystals
Stéphane Guillet, Alexis Poncet, Marine Le Blay +3
When soft matter is driven out of equilibrium its constituents interact via effective interactions that escape Newton's action-reaction principle. Prominent examples include the hy…
Interpreting neural operators: how nonlinear waves propagate in non-reciprocal solids
Jonathan Colen, Alexis Poncet, Denis Bartolo +1
We present a data-driven pipeline for model building that combines interpretable machine learning, hydrodynamic theories, and microscopic models. The goal is to uncover the underly…
Active hydraulics laws from frustration principles
Camille Jorge, Amélie Chardac, Alexis Poncet +1
Viscous flows are laminar and deterministic. Robust linear laws accurately predict their streamlines in structures as complex as blood vessels, porous media and pipe networks. Howe…
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…
When soft crystals defy Newton's third law: Non-reciprocal mechanics and dislocation motility
Alexis Poncet, Denis Bartolo
The effective interactions between the constituents of driven soft matter generically defy Newton's third law. Combining theory and numerical simulations, we establish that six cla…
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,…
Motile dislocations knead odd crystals into whorls
Ephraim S. Bililign, Florencio Balboa Usabiaga, Yehuda A. Ganan +6
The competition between thermal fluctuations and potential forces is the foundation of our understanding of phase transitions and matter in equilibrium. Driving matter out of equil…
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…
Universal non-Debye scaling in the density of states of amorphous solids
Patrick Charbonneau, Eric I. Corwin, Giorgio Parisi +2
At the jamming transition, amorphous packings are known to display anomalous vibrational modes with a density of states (DOS) that remains constant at low frequency. The scaling of…
