Chemically Induced Nanoscale Josephson Effects in Non-Stoichiometric High-Temperature Superconductors
Sergei Sergeenkov
This paper reviews some of the recently suggested (by the author) novel effects expected to occur in intrinsically granular non-stoichiometric material modeled by 2D Josephson junc…
On Critical Current Enhancement in Dislocated, Deoxygenated and Particle Irradiated Superconductors: A Unified Approach
Sergei Sergeenkov
A unified approach for description of the anomalous critical current enhancement in dislocated, deoxygenated, and particle irradiated superconductors is proposed based on a novel c…
Novel Effects in High-Tc Granular Superconductors Predicted via Model of 3D Josephson Junction Arrays
Sergei Sergeenkov
Despite the fact that Josephson Junction Arrays (JAA) have been actively studied for decades, they continue to contribute to the variety of intriguing and peculiar phenomena (both…
Phase dependent differential thermopower of SND junctions: Pair-breaking effects and Gaussian fluctuations
Sergei Sergeenkov, Marcel Ausloos
We start with revisiting our previous results on thermoelectric response of SNS configuration in a C-shaped Bi(x)Pb(1-x)Sr(2)CaCu(2)O(y) sample in order to include strong fluctuati…
Magnetic Field Induced Charging Effects in Josephson Junction Arrays
Sergei A. Sergeenkov
A magnetic field induced electric polarization and the corresponding change of an effective junction capacitance are considered within a 3D model of disordered Josephson junction a…
Probing mixed s+id pairing state via thermoelectric response of SND junction
Sergei Sergeenkov
The thermoelectric response of SND configuration is considered within the generalized Ginzburg-Landau theory for a homogeneous admixture of s-wave and d-wave superconductors. The r…
