We study sample-to-sample fluctuations of the gap ratio in energy spectra finite disordered spin chains. The chains are described by random-field Ising model and Heisenberg model. show that away from ergodic-nonergodic crossover, correctly captured Rosenzweig-Porter (RP) However, microscopic models significantly exceed those RP vicinity crossover. upon introducing an extension to model, one rep...

We study the crossover scaling behavior of the height-height correlation function in interface depinning in random media. We analyze experimental data from a fracture experiment and simulate an elastic line model with nonlinear couplings and disorder. Both exhibit a crossover between two different universality classes. For the experiment, we fit a functional form to the universal crossover scal...

We propose a computational model that is inspired by genetic operations over strings such as mutation and crossover. The model, Accepting Network of Genetic Processors, is highly related to previously proposed ones such as Networks of Evolutionary Processors and Networks of Splicing Processors. These models are complete computational models inspired by DNA evolution and recombination. Here, we ...
