On the continuity of the SRB entropy for endomorphisms
Jose F. Alves, Krerley Oliveira, Ali Tahzibi
We consider classes of dynamical systems admitting Markov induced maps. Under general assumptions, which in particular guarantee the existence of SRB measures, we prove that the en…
Experimental observation of superluminal group velocities in bulk two-dimensional photonic bandgap crystals
D. R. Solli, C. F. McCormick, R. Y. Chiao +1
We have experimentally observed superluminal and infinite group velocities in bulk hexagonal two-dimensional photonic bandgap crystals with bandgaps in the microwave region. The gr…
Stochastic description of the dynamics of the random-exchange Heisenberg chain
M. H. Vainstein, R. Morgado, F. A. Oliveira +2
We study the diffusion process in a Heisenberg chain with correlated spatial disorder, with a power spectrum in the momentum space behaving as , using a stochastic descript…
Damage spreading in the Bak-Sneppen model: Sensitivity to the initial conditions and equilibration dynamics
U. Tirnakli, M. L. Lyra
The short-time and long-time dynamics of the Bak-Sneppen model of biological evolution are investigated using the damage spreading technique. By defining a proper Hamming distance…
