Linear and nonlinear flux dynamics in multilayered Bi₂Sr₂CaCu₂Ox single crystals

For an anisotropic, multilayered superconductor of the BSCCO type or a low Tc Josephson stack, the linear plasma resonances are derived theoretically using the inductive coupling model. The eigenmodes of these plasma oscillations are discussed. It is shown that symmetries from the plasma dispersion relation and the dynamic properties of the vortices are closely connected and we predict from this analysis the vortex excitations that are otherwise only obtainable from numerical simulations. The model assumes that vortices and an applied magnetic field are parallel to the planes.
