  2. 16. Roughening in dimer models : Random matrix statistics and surface fluctuations

    Author : Scott Mason; Kurt Johansson; Alexey Bufetov; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Matematik; Mathematics;

    Abstract : The field of mathematical statistical mechanics sits at the intersection of probability theory and mathematical physics. It consists of the rigorous analysis of models in statistical mechanics, such as dimer and lattice models - of which the Ising model is a classical example. READ MORE
