Description

The dynamics of vortices near depinning transition is studied in terms of a three-dimensional flux-line model with point-like pinning centers. The zero-temperature critical depinning force Fc0 is determined with two methods consistently. We find two universal exponents β∼0.64 and δ∼2.3 which characterize the critical behaviors of depinning transition of Bragg glass (BrG). The dynamical modes of flux lines near Fc0 are also discussed.
