A multi-scale based cohesive zone model for the analysis of thickness scaling effect in fiber bridging

A cohesive zone model (CZM) is proposed to assess the thickness scaling effect associated with fiber bridging during fracture. The CZM was developed through a multi-scale simulation approach and utilizes an embedded cell model of the Double Cantilever Beam ...

Critical Josephson current in the dynamical Coulomb blockade regime

Klaus Kern, Markus Etzkorn, Matthias Alexander Eltschka, Maximilian Assig

The current-voltage characteristics of a voltage-biased Josephson junction in the low conductance regime of an ultra-low temperature scanning tunneling microscope (STM) is dominated by sequential charge tunneling. Using P(E) theory we show that the Josephs ...

A nanoscale gigahertz source realized with Josephson scanning tunneling microscopy

Klaus Kern, Markus Etzkorn, Matthias Alexander Eltschka, Maximilian Assig

Using the AC Josephson effect in the superconductor-vacuum-superconductor tunnel junction of a scanning tunneling microscope (STM), we demonstrate the generation of GHz radiation. With the macroscopic STM tip acting as a lambda/4-monopole antenna, we first ...

Josephson Tunneling at the Atomic Scale

Berthold Jäck

The aim of this thesis is to characterize the properties of a Josephson junction in a Scanning Tunneling Microscope (STM) at millikelvin temperatures and to implement Josephson STM (JSTM) as a versatile probe at the atomic scale. To this end we investigate ...

Connecting strongly correlated superfluids by a quantum point contact

Jean-Philippe Brantut, Thierry Giamarchi

Point contacts provide simple connections between macroscopic particle reservoirs. In electric circuits, strong links between metals, semiconductors, or superconductors have applications for fundamental condensed-matter physics as well as quantum informati ...

Kerr coefficients of plasma resonances in Josephson junction chains

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 model for ...

Intrinsic Josephson junctions in the iron-based multi-band superconductor (V 2 Sr 4 O 6 )Fe 2 As 2

Philip Johannes Walter Moll

In layered superconductors, Josephson junctions may be formed within the unit cell1,2,3 as a result of sufficiently low inter-layer coupling. These intrinsic Josephson junction (iJJ) systems4 have attracted considerable interest for their application poten ...

Experimental visualization of scattering at defects in electronic transport through a single atomic junction

Klaus Kern, Peter Wahl

For electronic transport at the nanoscale, coherent scattering at defects plays an important role. Therefore, the capability of visualizing the influence of defects on the conductivity of single atomic junctions may benefit the development of future nano-e ...
