Critical fluctuations in the breakdown of disordered systems
Alberto Petri
In this paper some critical aspects of the behaviour of breaking lattices subject to slow driving forces are briefly reviewed. In particular fluctuations in the response to the var…
Dynamic Fracture Model for Acoustic Emission
Manuela Minozzi, Guido Caldarelli, Luciano Pietronero +1
We study the acoustic emission produced by micro-cracks using a two-dimensional disordered lattice model of dynamic fracture, which allows to relate the acoustic response to the in…
A microscopic 2D lattice model of dimer granular compaction with friction
C. Fusco, A. Fasolino, P. Gallo +2
We study by Monte Carlo simulation the compaction dynamics of hard dimers in 2D under the action of gravity, subjected to vertical and horizontal shaking, considering also the case…
Anelastic relaxation process of polaronic origin in La{2-x}Sr{x}CuO{4}: interaction between the charge stripes and pinning centers
F. Cordero, A. Paolone, R. Cantelli +1
The evolution of an anelastic relaxation process occurring around 80 K in La{2-x}Sr{x}CuO{4} at a measuring frequency of ~1 kHz has been followed from x = 0.0075 to the overdoped r…
Cumulants of the three state Potts model and of nonequilibrium models with C3v symmetry
Tania Tome, Alberto Petri
The critical behavior of two-dimensional stochastic lattice gas models with C3v symmetry is analyzed. We study the cumulants of the order parameter for the three state (equilibrium…
Anelastic spectroscopy study of the spin-glass and cluster spin-glass phases of LaSrCuO
A. Paolone, F. Cordero, R. Cantelli +1
The anelastic spectra of LaSrCuO have been measured at liquid He temperatures slightly below and above the concentration which is considere…
Acoustic measurement of the low-energy excitations in Nd2-xCexCuO4
F. Cordero, C. R. Grandini, M. Ferretti
The complex dynamic Young's modulus of ceramic Nd2-xCexCuO4 with x = 0, 0.05 and 0.20 has been measured from 1.5 to 100 K at frequencies of 1-10 kHz. In the undoped sample the modu…
