Learning to outgrow the competition: reaction-diffusion systems that adapt to time-dependent environments
Olivier Rivoire, Guy Bunin
A fundamental challenge in both biology and engineering is understanding how adaptation can emerge from simple physical or chemical building blocks. Biological adaptation appears t…
Evolutionary features in a minimal physical system: diversity, selection, growth, inheritance, and adaptation
Guy Bunin, Olivier Rivoire
We present a simple physical model that recapitulates several features of biological evolution, while being based only on thermally-driven attachment and detachment of elementary b…
One-way catalysis in a solvable lattice model
Sara Mahdavi, Yann Sakref, Olivier Rivoire
Catalysts speed up chemical reactions with no energy input and without being transformed in the process, therefore leaving equilibrium constants unchanged. Some catalysts, however,…
Design principles, growth laws, and competition of minimal autocatalysts
Yann Sakref, Olivier Rivoire
The apparent difficulty of designing simple autocatalysts that grow exponentially in the absence of enzymes, external drives or ingenious internal mechanisms severely constrains sc…
On the exclusion of exponential autocatalysts by sub-exponential autocatalysts
Yann Sakref, Olivier Rivoire
Selection among autocatalytic species fundamentally depends on their growth law: exponential species, whose number of copies grows exponentially, are mutually exclusive, while sub-…
