Thermodynamics of Evolutionary Games

open access: yes, 2018
How cooperation can evolve between players is an unsolved problem of biology. Here we use Hamiltonian dynamics of models of the Ising type to describe populations of cooperating and defecting players to show that the equilibrium fraction of cooperators ...

RNA secondary structure formation: a solvable model of heteropolymer folding

open access: yes, 1999
The statistical mechanics of heteropolymer structure formation is studied in the context of RNA secondary structures. A designed RNA sequence biased energetically towards a particular native structure (a hairpin) is used to study the transition between ...
