Self-organized digital disorder of Davydov's beta kink
Abstract
Description
I discuss the digital disorder introduced by Rosu and Canessa [Phys. Rev. E 47, R3818 (1993)] in the Davydov model of energy diffusion along α-helix protein chains. The digitally disordered Davydov beta kinks display self-organized features, i.e., power law correlations both in time and space, that may be attributed to incipient dynamic structural changes of the protein chain as a consequence of coarse-graining the fluctuations due to microscopic degrees of freedom. In this paper, I provide a simple semiconductor model for the flicker noise and also comment on the multifractality that one may associate with the protein chains by means of digital disorder
