Average yielding and weakest link statistics in micron-scale plasticity
Péter Dusán Ispánovity, Ádám Hegyi, István Groma +3
Micron-scale single crystalline materials deform plastically via large intermittent strain bursts that make the deformation process unpredictable. Here we investigate this stochast…
Criticality of relaxation in dislocation systems
Péter Dusán Ispánovity, István Groma, Géza Györgyi +2
Relaxation processes of dislocation systems are studied by two-dimensional dynamical simulations. In order to capture generic features, three physically different scenarios were st…
Renormalization flow in extreme value statistics
Eric Bertin, Géza Györgyi
The renormalization group transformation for extreme value statistics of independent, identically distributed variables, recently introduced to describe finite size effects, is pre…
Submicron plasticity: yield stress, dislocation avalanches, and velocity distribution
Péter Dusán Ispánovity, István Groma, Géza Györgyi +2
The existence of a well defined yield stress, where a macroscopic piece of crystal begins to plastically flow, has been one of the basic observations of materials science. In contr…
Renormalization group theory for finite-size scaling in extreme statistics
G. Gyorgyi, N. R. Moloney, K. Ozogany +2
We present a renormalization group (RG) approach to explain universal features of extreme statistics, applied here to independent, identically distributed variables. The outlines o…
Maximal height statistics for 1/f^alpha signals
G. Gyorgyi, N. R. Moloney, K. Ozogany +1
Numerical and analytical results are presented for the maximal relative height distribution of stationary periodic Gaussian signals (one dimensional interfaces) displaying a 1/f^al…
