From Random Walks to Thermal Rides: Universal Anomalous Transport in Soaring Flights
Jérémie Vilpellet, Alexandre Darmon, Michael Benzaquen
Cross-country soaring flights rely on intermittent atmospheric updrafts to cover long distances, producing trajectories that alternate between rapid relocation and local exploratio…
Harmonious Color Pairings: Insights from Human Preference and Natural Hue Statistics
Ortensia Forni, Alexandre Darmon, Michael Benzaquen
While color harmony has long been studied in art and design, a clear consensus remains elusive, as most models are grounded in qualitative insights or limited datasets. In this wor…
Multiscale Relevance of Natural Images
Samy Lakhal, Alexandre Darmon, Iacopo Mastromatteo +2
We use an agnostic information-theoretic approach to investigate the statistical properties of natural images. We introduce the Multiscale Relevance (MSR) measure to assess the rob…
A New Spin on Color Quantization
Samy Lakhal, Alexandre Darmon, Michael Benzaquen
We address the problem of image color quantization using a Maximum Entropy based approach. Focusing on pixel mapping we argue that adding thermal noise to the system yields better…
Beauty and structural complexity
Samy Lakhal, Alexandre Darmon, Jean-Philippe Bouchaud +1
We revisit the long-standing question of the relation between image appreciation and its statistical properties. We generate two different sets of random images well distributed al…
A change in stripes for cholesteric shells via anchoring in moderation
Lisa Tran, Maxim O. Lavrentovich, Guillaume Durey +7
Chirality, ubiquitous in complex biological systems, can be controlled and quantified in synthetic materials such as cholesteric liquid crystal (CLC) systems. In this work, we stud…
Elastic interactions between topological defects in chiral nematic shells
Alexandre Darmon, Olivier Dauchot, Teresa Lopez-Leon +1
We present a novel, self-consistent and robust theoretical model to investigate elastic interactions between topological defects in liquid crystal shells. Accounting for the non-co…
Topological defects in cholesteric liquid crystal shells
Alexandre Darmon, Michael Benzaquen, Simon Čopar +2
We investigate experimentally and numerically the defect configurations emerging when a cholesteric liquid crystal is confined to a spherical shell. We uncover a rich scenario of d…
Waltzing route towards double-helix formation in cholesteric shells
Alexandre Darmon, Michael Benzaquen, Olivier Dauchot +1
We study cholesteric order in liquid crystal shells with planar degenerate anchoring. We observe that the bipolar and radial configurations intensively reported for bulk droplets h…
Spherical nematics with a threefold valence
Vinzenz Koning, Teresa Lopez-Leon, Alexandre Darmon +2
We present a theoretical study of the energetics of thin nematic shells with two charge one-half defects and one charge-one defect. We determine the optimal arrangement: the defect…
Two-phase flow in a chemically active porous medium
Alexandre Darmon, Michael Benzaquen, Thomas Salez +1
We study the problem of the transformation of a given reactant species into an immiscible product species, as they flow through a chemically active porous medium. We derive the equ…
Wake pattern and wave resistance for anisotropic moving objects
Michael Benzaquen, Alexandre Darmon, Elie Raphaël
We present a theoretical study of gravity waves generated by an anisotropic moving disturbance. We model the moving object by an elliptical pressure field of given aspect ratio $\m…
Kelvin wake pattern at large Froude numbers
Alexandre Darmon, Michael Benzaquen, Elie Raphaël
Gravity waves generated by an object moving at constant speed at the water surface form a specific pattern commonly known as the Kelvin wake. It was proved by Lord Kelvin that such…
