1. 16. Using Coding Techniques for Attacking Post-Quantum Cryptographic Assumptions and Systems

   Författare :Qian Guo; Institutionen för elektro- och informationsteknik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Post-quantum cryptography for resisting possible attacks from malicious quantum adversaries has become one of the key topics in recent cryptographic research. Its ultimate goal is to search for efficient and secure primitives replacing the factoring- and discrete log-based schemes in service that will be broken in polynomial time by Shor’s algorithm.

3. 17. B-physics potential of the ATLAS experiment and performance of the ATLAS Transition Radiation Tracker

   Författare :Chafik Driouichi; Teoretisk partikelfysik - Geonomgår omorganisation; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS; B-physics; LHC; Bc meson; Elementary particle physics; Transition Radiation Tracker; quantum field theory; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:2004:Driouichi;

   Sammanfattning : The ATLAS experiment is one of the four experiments at the Large Hadron Collider (LHC), which is supposed to be operational in early 2007. Proton-proton collisions at an unprecedented center-of-mass energy of 14 TeV will probe new frontiers of the universe, hopefully providing a better understanding of the laws governing our universe.

4. 18. Astrophysical probes of axionlike particles

   Författare :Eike Christoph Ravensburg; M. C. David Marsh; Frank Wilczek; Joerg Jaeckel; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; astroparticle physics; axions; supernovae; physics beyond the standard model; dark matter; Theoretical Physics; teoretisk fysik;

   Sammanfattning : This thesis is a contribution to the search for new fundamental physics in the form of axionlike particles (ALPs). ALPs are relatively light and feebly interacting particles that are part of many theories extending the Standard Model of particle physics, e.g. LÄS MER

5. 19. Feasibility study of resonant antiproton capture by ions and an open system approach to resonance decay

   Författare :Michael Genkin; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atomic physics; Atomfysik;

   Sammanfattning : The present thesis is based on two different projects. The first part deals withresonant capture of antiprotons by electron excitation in highly charged hydrogenlike ions. LÄS MER

7. 20. Relativistic effects in Compton scattering of photons from bound electron states

   Författare :A. Roland Ribberfors; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : What is light? A correct answer to this question is: I don't know, but I can see some of its properties"! It is exciting to study such a complex thing and to search for models which can help us to try to understand, in a proper way, some of the most interesting behavior of light. We see the sunshine and the radiation makes us warm, undoubtly it must be some kind of energy? Interference experiments with monochromatic light show that the radiation has wave-like properties, but for example scattering experiments predict a particle nature. LÄS MER
