Myocardial ischemia is a pathophysiological state characterized by inadequate perfusion of the myocardium, resulting in an imbalance between myocardial oxygen demand and supply. It is most commonly caused by coronary artery disease, in which atherosc

Bloch band dynamics of a Josephson junction in an inductive environment

Autor: Thomas Weißl, Olivier Buisson, Ioan Pop, Frank W. J. Hekking, Gianluca Rastelli, Wiebke Guichard, Iulian Matei

We have measured the current-voltage characteristics of a Josephson junction with tunable Josephson energy $E_J$ embedded in an inductive environment provided by a chain of SQUIDs. Such an environment induces localization of the charge on the junctio

By adding a large inductance in a dc-SQUID phase qubit loop, one decouples the junctions' dynamics and creates a superconducting artificial atom with two internal degrees of freedom. In addition to the usual symmetric plasma mode ({\it s}-mode) which

Structural and electronic properties of electron-doped Sr1−xLaxCuO2 epitaxial thin films grown by sputtering

Autor: Iulian Matei, Zhi Zhong Li, Helene Raffy

Publikováno v: Physica C: Superconductivity and its Applications. :452-453

We report on the synthesis of electron-doped Sr 1− x La x CuO 2 thin films by a sputtering technique. Single phase c -axis oriented thin films were epitaxially grown on various oxide substrates, with better results on DyScO 3 and KTaO 3 . Our preli

We present an experimental and theoretical analysis of the self- and cross-Kerr effect of extended plasma resonances in Josephson junction chains. We calculate the Kerr coefficients by deriving and diagonalizing the Hamiltonian of a linear circuit mo

We present a novel shadow evaporation technique for the realization of junctions and capacitors. The design by e-beam lithography of strongly asymmetric undercuts on a bilayer resist enables in situ fabrication of junctions and capacitors without the
