Mutation-Selection Balance: Ancestry, Load, and Maximum Principle
Joachim Hermisson, Oliver Redner, Holger Wagner +1
We show how concepts from statistical physics, such as order parameter, thermodynamic limit, and quantum phase transition, translate into biological concepts in mutation-selection…
The control of phenotype: connecting enzyme variation to physiology
Homayoun Bagheri-Chaichian, Joachim Hermisson, Juozas R. Vaisnys +1
Metabolic control analysis (Kacser & Burns (1973). Symp. Soc. Exp. Biol. 27, 65-104; Heinrich & Rapoport (1974). Eur. J. Biochem. 42, 89-95) was developed for the understanding of…
Four-state quantum chain as a model of sequence evolution
Joachim Hermisson, Holger Wagner, Michael Baake
A variety of selection-mutation models for DNA (or RNA) sequences, well known in molecular evolution, can be translated into a model of coupled Ising quantum chains. This correspon…
Aperiodic and correlated disorder in XY-chains: exact results
Joachim Hermisson
We study thermodynamic properties, specific heat and susceptibility, of XY quantum chains with coupling constants following arbitrary substitution rules. Generalizing an exact reno…
