Phase Transitions in Systems of Interacting Species
Margarita Ifti, Birger Bergersen
We discuss an autocatalytic reaction system: the cyclic competition model A1 + A2 --> 2 A2, A2 + A3 --> 2 A3, A3 + A4 --> 2 A4, A4 + A1 --> 2 A1), as well as its neutral counterpar…
First passage times of pulling-assisted DNA unzipping
G. Lakatos, T. Chou, B. Bergersen +1
We investigate the voltage-driven transport of hybridized DNA through membrane channels. As membrane channels are typically too narrow to accommodate hybridized DNA, the dehybridiz…
Crossover Behaviour of 3-Species Systems with Mutations or Migrations
Margarita Ifti, Birger Bergersen
We study the ABC model in the cyclic competition and neutral drift versions, with mutations and migrations introduced into the model. When stochastic phenomena are taken into accou…
Survival and Extinction in Cyclic and Neutral Three--Species Systems
Margarita Ifti, Birger Bergersen
We study the ABC model (A + B --> 2B, B + C --> 2C, C + A --> 2A), and its counterpart: the three--component neutral drift model (A + B --> 2A or 2B, B + C --> 2B or 2C, C + A -->…
Correlations in Ising chains with non-integrable interactions
B. Bergersen, Z. Racz, H. -J. Xu
Two-spin correlations generated by interactions which decay with distance r as r^{-1-sigma} with -1 <sigma <0 are calculated for periodic Ising chains of length L. Mean-field theor…
