Abstract

The results of numeric simulations of nonisothermal dendritic flux penetration in type-II superconductors were reported. A generic mechanism of dynamic branching of a propogating hot spot of a flux flow/normal state triggered by a local heat pulse was proposed. The hot spot underwent a cascade of successive splittings giving rise to a dissipative dendritic-type flux structure.
