2. 1. Simulations of thermoelectric transport in granularsuperconductors

   Author : Andreas Andersson; Jack Lidmar; Vladimir Krasnov; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Superconductivity; Supraledning;

   Abstract : This thesis presents results from numerical simulations of the Nernst effect dueto phase fluctuations in models of two-dimensional granular superconductors. Inaddition other transport properties, such as thermal conductivity and electrical re-sistivity are calculated. READ MORE

4. 2. Superradiant THz wave emission from arrays of Josephson junctions

   Author : Ievgenii Borodianskyi; Vladimir Krasnov; Yury Shukrinov; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Josephson junction; Superconductor; ThZ emission; high-Tc; Physics; fysik;

   Abstract : High-power, continuous-wave, compact and tunable THz sources are needed for a large variety of applications. Development of power-efficient sources of electromagnetic radiation in the 0.1-10 THz range is a difficult technological problem, known as the “THz gap. READ MORE

5. 3. Vortex-matter in Multi-component Superconductors

   Author : Johan Carlström; Mats Wallin; Vladimir Krasnov; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Superconductivity;

   Abstract : The topic of this thesis is vortex-physics in multi component Ginzburg- Landau models. These models describe a newly discovered class of supercon- ductors with multiple superconducting gaps, and posses many properties that set them apart from single component models. READ MORE

6. 4. Pulsed laser deposition and nanofabrication of mesoscopic devices based on cuprates and manganites

   Author : Roberto de Andrés Prada; Vladimir M. Krasnov; Christian Bernhard; Taras Golod; Dag Winkler; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cuprates; manganites; pulsed laser deposition; nano-fabrication; heterostructures; fysik; Physics;

   Abstract : This thesis explores the growth, the nano-fabrication and the study of the magneto-transport properties of Superconductor/Ferromagnet/Superconductor (SFS) structures from complex oxides such as the high Tc superconducting cuprate YBa2Cu3O7 (YBCO) and the ferromagnetic manganites La2/3Ca1/3MnO3 and La2/3Sr1/3MnO3 (LCMO and LSMO), deposited with the pulsed laser deposition (PLD) technique.The present work has been possible thanks to the collaboration between the “Magnetism and Superconductivity” Group at the University of Fribourg, in Switzerland, and the “Experimentell Kondenserade Materiens Fysik” Group at Stockholm University, in Sweden.

7. 5. Fabrication and Characterization of Superconductive Coplanar Waveguide Resonators : Fabrication and Characterization of Superconductive Coplanar Waveguide Resonators

   Author : Adem Ergül; David B. Haviland; Vladimir Krasnov; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coplanar; Waveguide; Resonator; Superconductive; Fabrication; Characterization; Superconductivity; Supraledning;

   Abstract : The objective of this thesis is to evaluate a generic process for fabrication and characterization of the Superconductive coplanar waveguide (CPW) resonators. Superconductive CPW resonators with various lengths and shapes are designed to investigate their electrical and magnetic properties as well as resonance properties and sensitivities. READ MORE
