2. 16. Quantum optics with artificial atoms

   Author : Anton Frisk Kockum; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; surface acoustic waves; transmon; circuit QED; photon detector; parity measurement; quantum stochastic calculus; Quantum optics; artificial atoms; quantum measurement;

   Abstract : Quantum optics is the study of interaction between atoms and photons. In the eight papers of this thesis, we study a number of systems where artificial atoms (here, superconducting circuits emulating the level structure of an atom) enable us to either improve on known concepts or experiments from quantum optics with natural atoms, or to explore entirely new regimes which have not been possible to reach in such experiments.

4. 17. Quantum effects in nanoscale Josephson junction circuits

   Author : Silvia Corlevi; David B. Haviland; Jukka Pekola; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Josephson junctions; Josephson junction arrays; electromagnetic environment; Cooper pair transistor; parity effects; Physics; Fysik;

   Abstract : This thesis presents the results of an experimental study on single-charge effects in nanoscale Josephson junctions and Cooper pair transistors (CPTs). In nanoscale Josephson junctions the charging energy EC becomes significant at sub-Kelvin temperatures and single-charge effects, such as the Coulomb blockade of Cooper pair tunneling, influence the transport properties.

5. 18. Essays on Purchasing Power Parity, Real Exchange Rate, and Optimum Currency Areas

   Author : Beatrice Kalinda Mkenda; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Abstract : This thesis contains three separate papers. Paper I tests whether the theory of Purchasing Power Parity holds in a selected sample of twenty African countries. The paper employs a panel unit root test to test whether the real exchange rates in the panel are mean reverting or not. The test employed is the Im et al (1997) test. READ MORE

6. 19. Towards a Theory of Codes for Iterative Decoding

   Author : Michael Lentmaier; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bit error probability; low-density parity-check convolutional code; low-density parity-check code; turbo code; convolutional code; channel coding; iterative decoding; Informatics; systems theory; Informatik; systemteori;

   Abstract : Channel codes in combination with iterative decoding techniques are a both powerful and efficient method to protect data against disturbances in digital communication systems. This thesis deals with various code constructions for block-wise and continuous transmission that have the potential to achieve low bit error rates with iterative decoding, even when operating close to the Shannon limit.

7. 20. Graphical representations of Ising and Potts models : Stochastic geometry of the quantum Ising model and the space-time Potts model

   Author : Jakob Erik Björnberg; Anders Björner; Jeffrey Steif; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum Ising model; Ising model; Potts model; random-cluster model; random-current representation; random-parity representation; differential inequality; phase transition; Discrete mathematics; Diskret matematik;

   Abstract : HTML clipboard Statistical physics seeks to explain macroscopic properties of matter in terms of microscopic interactions. Of particular interest is the phenomenon of phase transition: the sudden changes in macroscopic properties as external conditions are varied. READ MORE
