    Sammanfattning : In the eld of particle systems and growths models simulation is an importanttool. When explicit calculations are too complex or impossibleto perform we may use simulations instead. We adapt a new techniquehere denoted omniparametric simulation, to the two-type Richardson,Ising and Potts models. LÄS MER

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

    Detta är en avhandling från Stockholm : US AB

    Författare :Jakob Erik Björnberg; Anders Björner; Jeffrey Steif; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum Ising model; Ising model; Potts model; random-cluster model; random-current representation; random-parity representation; differential inequality; phase transition; MATHEMATICS Algebra; geometry and mathematical analysis Discrete mathematics; MATEMATIK Algebra; geometri och analys Diskret matematik;

    Sammanfattning : 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. LÄS MER

  3. 3. Gibbs Measures and Phase Transitions in Potts and Beach Models

    Detta är en avhandling från Stockholm : Matematik

    Författare :Per Hallberg; [2004]
    Nyckelord :Potts model; beach model; percolation; random-cluster model; Gibbs measure; coupling; Markov chains on infinite trees; critical exponent;

    Sammanfattning : The theory of Gibbs measures belongs to the borderlandbetween statistical mechanics and probability theory. In thiscontext, the physical phenomenon of phase transitioncorresponds to the mathematical concept of non-uniqueness for acertain type of probability measures.The most studied model in statistical mechanics is thecelebrated Ising model.
