Domain convexification: a simple model for invasion processes
David Martin-Calle, Olivier Pierre-Louis
We propose an invasion model where domains grow up to their convex hulls and merge when they overlap. This model can be seen as a continuum and isotropic counterpart of bootstrap p…
Accurate generation of stochastic dynamics based on multi-model Generative Adversarial Networks
Daniele Lanzoni, Olivier Pierre-Louis, Francesco Montalenti
Generative Adversarial Networks (GANs) have shown immense potential in fields such as text and image generation. Only very recently attempts to exploit GANs to statistical-mechanic…
Temperature transitions and degeneracy in the control of small clusters with a macroscopic field
Francesco Boccardo, Olivier Pierre-Louis
We present a numerical investigation of the control of few-particle fluctuating clusters with a macroscopic field. Our goal is to reach a given target cluster shape is minimum time…
Equilibrium return times of small fluctuating clusters and vacancies
Francesco Boccardo, Younes Benamara, Olivier Pierre-Louis
The expected return time of a fluctuating two-dimensional cluster or vacancy to a given configuration is studied in thermodynamic equilibrium. We define a family of bond-breaking m…
Controlling the shape of small clusters with and without macroscopic fields
Francesco Boccardo, Olivier Pierre-Louis
Despite major advances in the understanding of the formation and dynamics of nano-clusters in the past decades, theoretical bases for the control of their shape are still lacking.…
Interface collisions with diffusive mass transport
Bastien Marguet, F. D. A. Aarão Reis, Olivier Pierre-Louis
We report on a linear Langevin model that describes the evolution of the roughness of two interfaces that move towards each other and are coupled by a diffusion field. This model a…
Growth at high substrate coverage can decrease the grain boundary roughness of 2D materials
Fabio D. A. Aarão Reis, Bastien Marguet, Olivier Pierre-Louis
Grain boundary roughness can affect electronic and mechanical properties of two-dimensional materials. This roughness depends crucially on the growth process by which the two-dimen…
Crystal growth in confinement
Felix Kohler, Olivier Pierre-Louis, Dag Kristian Dysthe
The growth of crystals confined in porous or cellular materials is ubiquitous in Nature and industry. Confinement affects the formation of biominerals in living organisms, of miner…
Shear dynamics of confined membranes
Thomas Le Goff, Tung B. T. To, Olivier Pierre-Louis
We model the nonlinear response of a lubricated contact composed of a two-dimensional lipid membrane immersed in a simple fluid between two parallel flat and porous walls under she…
Controlling anisotropy in 2D microscopic models of growth
Luca Gagliardi, Olivier Pierre-Louis
The quantitative knowledge of interface anisotropy in lattice models is a major issue, both for the parametrization of continuum interface models, and for the analysis of experimen…
The Nonequilibrium Crystallization Force
Luca Gagliardi, Olivier Pierre-Louis
The forces exerted by growing crystals on the surrounding materials play a major role in many geological processes, from diagenetic replacement to rock weathering and uplifting of…
Confined Growth with slow surface kinetics: a Thin Film Model approach
Luca Gagliardi, Olivier Pierre-Louis
Recent experimental and theoretical investigations of crystal growth from solution in the vicinity of an impermeable wall have shown that: (i) growth can be maintained within the c…
Adhesion dynamics of confined membranes
Tung B. T. To, Thomas Le Goff, Olivier Pierre-Louis
We report on the modeling of the dynamics of confined lipid membranes. We derive a thin film model in the lubrication limit which describes an inextensible liquid membrane with ben…
Crystal growth in nano-confinement: Subcritical cavity formation and viscosity effects
Luca Gagliardi, Olivier Pierre-Louis
We report on the modeling of the formation of a cavity at the surface of crystals confined by a flat wall during growth in solution. Using a continuum thin film model, we discuss t…
Cavity formation in confined growing crystals
Felix Kohler, Luca Gagliardi, Olivier Pierre-Louis +1
Growing crystals form a cavity when placed against a wall. The birth of the cavity is observed both by optical microscopy of sodium chlorate crystals (NaClO) growing in the vic…
Thin film modeling of crystal dissolution and growth in confinement
Luca Gagliardi, Olivier Pierre-Louis
We present a continuum model describing dissolution and growth of a crystal contact confined against a substrate. Diffusion and hydrodynamics in the liquid film separating the crys…
Transition to coarsening for confined one-dimensional interfaces with bending rigidity
Thomas Le Goff, Paolo Politi, Olivier Pierre-Louis
We discuss the nonlinear dynamics and fluctuations of interfaces with bending rigidity under the competing attractions of two walls with arbitrary permeabilities. This system mimic…
Kink dynamics with oscillating forces
Thomas Le Goff, Olivier Pierre-Louis, Paolo Politi
It is well known that the dynamics of a one-dimensional dissipative system driven by the Ginzburg-Landau free energy may be described in terms of interacting kinks: two neighbourin…
Frozen states and order-disorder transition in the dynamics of confined membranes
Thomas Le Goff, Paolo Politi, Olivier Pierre-Louis
The adhesion dynamics of a membrane confined between two permeable walls is studied using a two-dimensional hydrodynamic model. The membrane morphology decomposes into adhesion pat…
Giant Slip at Liquid-Liquid Interfaces Using Hydrophobic Ball Bearings
Quentin Ehlinger, Laurent Joly, Olivier Pierre-Louis
Liquid-gas-liquid interfaces stabilized by hydrophobic beads behave as ball bearings under shear and exhibit a giant slip. Using a scaling analysis and molecular dynamics simulatio…
Nonlinear wavelength selection in surface faceting under electromigration
Fatima Barakat, Kirsten Martens, Olivier Pierre-Louis
We report on the control of the faceting of crystal surfaces by means of surface electromigration. When electromigration reinforces the faceting instability, we find perpetual coar…
Princess and the Pea at the nanoscale: Wrinkling and delamination of graphene on nanoparticles
Mahito Yamamoto, Olivier Pierre-Louis, Jia Huang +3
Thin membranes exhibit complex responses to external forces or geometrical constraints. A familiar example is the wrinkling, exhibited by human skin, plant leaves, and fabrics, res…
Dewetting of solid films with substrate mediated evaporation

The dewetting dynamics of an ultrathin film is studied in the presence of evaporation - or reaction - of adatoms on the substrate. KMC simulations are in good agreement with an ana…
Atomic step motion during the dewetting of ultra-thin films
