  1. 1. Propagation of Chaos for Kac-like Particle Systems

    Author : Dawan Mustafa; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : Master equations; chaotic densities; kinetic equations; propagation of chaos; Kac model; thermostatted master equation; Boltzmann equation; BGK equation; quenched process; uniform distribution; spectral gap; approximation process; kinetic equations;

    Abstract : This thesis concerns various aspects of the Kac model. The Kac model is a Markov jump process for a particle system where the total kinetic energy of the system is conserved. This particle model is connected to a limiting equation, describing the evolution of a one-particle density, when the numbers of particles tends to infinity. READ MORE

  2. 2. The Diversity and Unity of Reactor Noise Theory

    Author : Zhifeng Kuang; Chalmers University of Technology; []
    Keywords : neutron fluctuations; master equations; correlations; stochastic processes; the Langevin technique; power spectra; reactor noise; covariances;

    Abstract : The study of reactor noise theory concerns questions about cause and effect relationships, and the utilisation of random noise in nuclear reactor systems. The diversity of reactor noise theory arises from the variety of noise sources, the various mathematical treatments applied and the various practical purposes. READ MORE

  5. 5. Single-Electron Tunneling Spectroscopy in Magnetic Nanoparticles and Molecular Magnets

    Author : Lukasz Michalak; Fasta tillståndets fysik; []
    Keywords : master equation; magnetic nanoparticles; spin accumulation; molecular magnets; TMR; tunneling magnetoresistance; F-SET; ferromagnetic single-electron transistor; single-electron tunneling; nanomagnetism; spintronics; Coulomb blockade;

    Abstract : This thesis deals with single-electron tunneling in transistor-like devices in which the central electrode is either a metal nanoparticle (possibly ferromagnetic) or a molecular magnet. The investigated systems split into two different categories, depending on the size of the central island. READ MORE
