Boundary conditions and generation of periodic noise by a space-charge wave
Gor'kov L. P.
The excitation of oscillations by a moving space-charge wave is attributed to a nonlinear periodic regime which arises near a contact with a normal conductor. This regime corresponds to either a homogeneous phase slippage (thin samples) or a space-charge wave which is moving across the track of edge dislocations in the lattice. Some simple microscopic equations are proposed.
