1. 31. Structure of Deformed Proton-rich Nuclei Studied by Beta-decay

   Författare :Petter Urkedal; Matematisk fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical and general theoretical physics; classical mechanics; relativity; quantum mechanics; termodynamik; statistisk fysik; relativitet; kvantmekanik; klassisk mekanik; Matematisk och allmän teoretisk fysik; thermodynamics; gravitation; statistical physics; Physics; nuclear-structure beta-decay proton-rich drip-line neutrino; Fysik; Fysicumarkivet A:2002:Urkedal;

   Sammanfattning : Nuclear structure is studied using beta-decay reactions as a probe and focusing on medium-heavy proton-rich nuclei. One of the included articles is a systematic study covering a major part of the nuclear chart, especially searching for nuclei which may be sensitive to sub-MeV neutrinos... LÄS MER

3. 32. Hopf and Frobenius algebras in conformal field theory

   Författare :Carl Stigner; Jürgen Fuchs; Jens Fjelstad; Ingo Runkel; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; conformal field theory; category theory; Hopf algebra; Frobenius algebra; coends; mapping class group; defect lines; factorization constraints; Physics; Fysik;

   Sammanfattning : There are several reasons to be interested in conformal field theories in two dimensions. Apart from arising in various physical applications, ranging from statistical mechanics to string theory, conformal field theory is a class of quantum field theories that is interesting on its own. First of all there is a large amount of symmetries. LÄS MER

4. 33. A Matter of Disorder : Monte Carlo Simulations of Phase Transitions in Strongly Disordered Systems

   Författare :Marios Nikolaou; Mats Wallin; Asle Sudbø; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phase transitions; disorder; Monte Carlo simulations; superconductivity; Statistical physics; Statistisk fysik;

   Sammanfattning : Phase transitions and their critical scaling properties, especially in systems with disorder, are important both for our theoretical understanding of our environment, but also for their practical use in applications and materials in our everyday life. This thesis presents results from finite size scaling analysis of critical phenomena in systems with disorder, using high-precision Monte Carlo simulations and state of the art numerical methods.

5. 34. Searching for an Ultra High-Energy Diffuse Flux of Extraterrestrial Neutrinos with IceCube 40

   Författare :Henrik Johansson; Christian Walck; Antoine Letessier-Selvon; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neutrinos; UHE; diffuse; IceCube; Astroparticle physics; Astropartikelfysik; fysik; Physics;

   Sammanfattning : Neutrino astronomy has the potential to greatly improve our understanding of the high-energy universe. An unresolved, diffuse, flux of neutrinos is sensitive to the properties of the population of cosmic accelerators in the universe. LÄS MER

7. 35. Unveiling the nature of dark matter with direct detection experiments

   Författare :Vanessa Zema; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NaI; phenomenology; annual-modulation; direct-detection; cryogenics; COSINUS; polarised-nuclei; CRESST; dark-matter; phonons;

   Sammanfattning : The desire of discovery is an anthropic need which characterises and connects the human being over the eras. In particular, observing the sky is an instinctive drive exerted by the curiosity of the mysteries which it retains. LÄS MER
