Abstract

We present a phenomenological quantum theory for the c-axis charge dynamics in a 1D intrinsic Josephson-junction array with finite in-plane area. The plasma oscillations, which are stable in systems with large in-plane area, become unstable as the in-plane area decreases, which is caused by the Coulomb blockade effect. The critical in-plane area at which the instability takes place is determined on the basis of a renormalization group analysis.
