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…
Lee-Yang zeros for substitutional systems
Harald Simon, Michael Baake, Uwe Grimm
Qualitative and quantitative information about critical phenomena is provided by the distribution of zeros of the partition function in the complex plane. We apply this idea to Isi…
Ising spins on the labyrinth
Uwe Grimm, Michael Baake, Harald Simon
We consider a zero-field Ising model defined on a quasiperiodic graph, the so-called Labyrinth tiling. Exact information about the critical behaviour is obtained from duality argum…
