Query: $1/f$ noise and avalanche scaling in plastic deformation   We study the intermittency and noise of dislocation systems undergoing shear
deformation. Simulations of a simple two-dimensional discrete dislocation
dynamics model indicate that the deformation rate exhibits a power spectrum
scaling of the type $1/f^{\alpha}$. The noise exponent is far away from a
Lorentzian, with $\alpha \approx 1.5$. This result is directly related to the
way the durations of avalanches of plastic deformation activity scale with
their size.
