Subcritical crack growth: the microscopic origin of Paris's law
André P. Vieira, José S. Andrade, Hans J. Herrmann
We investigate the origin of Paris's law, which states that the velocity of a crack at subcritical load grows like a power law, , where is the stress inte…

Correlation amplitude and entanglement entropy in random spin chains
J. A. Hoyos, André P. Vieira, Nicolas Laflorencie +1
Using strong-disorder renormalization group, numerical exact diagonalization, and quantum Monte Carlo methods, we revisit the random antiferromagnetic XXZ spin-1/2 chain focusing o…

Characterization of welding defects by fractal analysis of ultrasonic signals
A. P. Vieira, E. P. de Moura, L. L. Goncalves +1
In this work we apply tools developed for the study of fractal properties of time series to the problem of classifying defects in welding joints probed by ultrasonic tecniques. We…
