Static Charge Coupling of Intrinsic Josephson Junction
Ch. Helm, J. Keller, Ch. Preis +1
A microscopic theory for the coupling of intrinsic Josephson oscillations due to charge fluctuations on the quasi two-dimensional superconducting layers is presented. Thereby in cl…
Phonons in intrinsic Josephson systems with parallel magnetic field
C. Preis, C. Helm, K. Schmalzl +3
Subgap resonances in the I-V curves of layered superconductors are explained by the coupling between Josephson oscillations and phonons with dispersion in c-direction. In the prese…
Interpretation of a microwave induced current step in a single intrinsic Josephson junction on a Bi-2223 thin film
Ch. Helm, A. Odagawa, M. Sakai +2
Thin stacks consisting of a single intrinsic Josephson junction on (Bi,Pb)-Sr-Ca-Cu-O thin films are investigated under the influence of external microwave fields. The --char…
Microscopic theory of the coupling of intrinsic Josephson oscillations and phonons
Ch. Preis, Ch. Helm, K. Schmalzl +2
A microscopic theory for the coupling of intrinsic Josephson oscillations and dispersive phonon branches in layered superconductors is developed. Thereby the effect of phonons on t…
