“…Helm et al 20,21 have developed a model describing the coupling between longitudinal phonons and intrinsic Josephson oscillations in cuprate superconductors, which, when sufficiently anisotropic, behave like stacks of underdamped Josephson junctions. [22][23][24] These theories have also been extended into the quantum regime. 25 In all the above calculations, each superconducting island was treated as a small object, with only two degrees of freedom: the phase of the superconducting order parameter, and the number of Cooper pairs on each island.…”

We present a model to describe an underdamped long Josephson junction coupled to a single-mode electromagnetic cavity, and carry out numerical calculations using this model in various regimes. The coupling may occur through either the electric or the magnetic field of the cavity mode. When a current is injected into the junction, we find that the time-averaged voltage exhibits self-induced resonant steps ͑SIRSs͒ due to coupling between the current in the junction and the electric field of the cavity mode. These steps are similar to those observed and calculated in small Josephson junctions. When a soliton is present in the junction ͑corresponding to a quantum of magnetic flux parallel to the junction plates͒, the SIRSs disappear if the electric field in the cavity is spatially uniform. If the cavity mode has a spatially varying electric field, there is a strong coupling between the soliton and the cavity mode. This coupling causes the soliton to become phase locked to the cavity mode, and produces steplike anomalies on the soliton branch of the I-V characteristics. If the coupling is strong enough, the frequency of the cavity mode is greatly redshifted from its uncoupled value. We present simple geometrical arguments which account for this behavior.

“…Layered high-T c superconductors (HTSC) represent natural stacks of atomic scale intrinsic Josephson junctions (IJJ's) [1]. Indeed, an interlayer spacing of 15.5Å was estimated from a periodic Fraunhofer modulation of Fiske steps in Bi-2212 mesas [2].…”

Operation of a Superconducting Quantum Interference Device (SQUID) made of stacked Josephson junctions is analyzed numerically for a variety of junction parameters. Due to a magnetic coupling of junctions in the stack, such a SQUID has certain advantages as compared to an uncoupled multi-junction SQUID. Namely, metastability of current-flux modulation can be reduced and a voltage-flux modulation can be improved if junctions in the stack are phase-locked. Optimum operation of the SQUID is expected for moderately long, strongly coupled stacked Josephson junctions. A possibility of making a stacked Josephson junction SQUID based on intrinsic Josephson junctions in high-Tc superconductor is discussed.

Phenomenology of conduction in incoherent layered crystals

A novel phenomenological approach to the analysis of the conductivities of incoherent layered crystals is presented. It is based on the fundamental relationship between the resistive anisotropy σ ab /σc and the ratio of the phase coherence lengths in the respective directions. We explore the model-independent consequences of a general assumption that the out-of-plane phase coherence length of single electrons is a short fixed distance of the order of interlayer spacing. Several topics are discussed: application of the scaling theory, magnetoresistivity, the effects of substitutions and the intermediate regime of conduction when both coherence lengths change with temperature, but at different rate.
