4. 2. Studies on hybrid superconducting junctions

   Author : Cecilia Holmqvist; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Critical Current; Single-Electron Box; Attractive Correlations; Josephson Junction; Negative Charging Energy; Quasiclassical Superconductivity; Josephson Current;

   Abstract : In the field of nanoelectronics, one seeks to combine quantum mechanical effects with macroscopic entities such as currents in order to find new ways of storing and manipulating information. One possibility to accomplish this is to use the quantum correlations found in superconductors. READ MORE

5. 3. Attractive Work : Nurses´ work in operating departments, and factors that make it attractive

   Author : Catrine Björn; Malin Josephson; Barbro Wadensten; Dag Rissén; Lotta Dellve; Uppsala universitet; []
   Keywords : attractive work; nursing workforce; personnel turnover; job satisfaction; nurse retention; nurse shortage; operating room; Caring Sciences; Vårdvetenskap;

   Abstract : Background: Previous studies show that nurse retention is one of the most effective strategies to counteract nursing shortages. Few studies have focused on the crucial resource of registered specialist nurses in operating departments. READ MORE

6. 4. Interactions and Interference in Mesoscopic Systems: Josephson Current through Quantum Dots and Josephson Junction Arrays

   Author : Klas Engström; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; density functional theory; quantum dots; Josephson effect; Andreev reflection; mesoscopic superconductivity; Josephson junction array; coulomb interactions; Bogoliubov-de Gennes equation; quantum phase transition;

   Abstract : The focus of the thesis is on the interplay between interactions and interference effects in mesoscopic systems. More specifically, the two main projects included deal with Coulomb interactions and Josephson effect in two superconductor-normal metal systems: (i) a Josephson junction array and (ii) a superconductor-normal metal-superconductor (SNS) system in which the normal part is a quantum dot.

7. 5. d-wave Josephson Junctions

   Author : Tobias Lindström; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Josephson junctions; high-temperature superconductivity; Andreev states;

   Abstract : The properties of d-wave YBCO Josephson junctions and dc-SQUIDs with high misorientation angles have beenstudied experimentally .The predominant d-wave symmetry of the pairing wavefunction in high-Tc superconductors has, to a large extent, beena hinderance in applications, but it also makes it possible to fabricate devices with novel properties that may be suitablefor applications in the quantum regime; one particulary interesting property is a strong second harmonic component in the current-phase relation ofjunctions with the electrodes oriented in a node-lobe arrangement; so-called 0-45 junctions.
