Comment on "Universal and accessible entropy estimation using a compression algorithm"
E. Brigatti, F. N. M. de Sousa Filho
In a recent Letter [1] a framework for estimating entropy was introduced and applied to one-dimensional and two-dimensional systems. In this Comment we show that the method is not…
Discontinuous transitions can survive to quenched disorder in a 2-dimensional nonequilibrium system
Minos A. Neto, E. Brigatti
We explore the effects that quenched disorder has on discontinuous nonequilibrium phase transitions into absorbing states. We focus our analysis on the Naming Game model, a nonequi…
An individual based model with global competition interaction: fluctuations effects in pattern formation
E. Brigatti, V. Schwammle, Minos A. Neto
We present some numerical results obtained from a simple individual based model that describes clustering of organisms caused by competition. Our aim is to show how, even when a de…
Nonextensive statistical mechanics: A brief introduction
Constantino Tsallis, Edgardo Brigatti
Boltzmann-Gibbs statistical mechanics is based on the entropy . It enables a successful thermal approach of ubiquitous systems, such as those in…
Quasi-stationary states in low-dimensional Hamiltonian systems
Fulvio Baldovin, Edgardo Brigatti, Constantino Tsallis
We address a simple connection between results of Hamiltonian nonlinear dynamical theory and thermostatistics. Using a properly defined dynamical temperature in low-dimensional sym…
