  5. 4. Numerical Renormalization, Doped Antiferromagnets, and Statistics - Topics in Low Dimensional Physics

    Författare :Martin Andersson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Josephson junctions; matrix-product states; fictitious flux; phase-separation; renormalization; stripes; t-J model; anyons; DMRG;

    Sammanfattning : The first part of the thesis deals with so called numerical renormalization group methods, and in particular the density-matrix renormalization group (DMRG). This method performs extremely well for large one-dimensional quantum systems like spin-chains and Hubbard models. LÄS MER

  7. 5. Abelian and non-abelian quantum Hall hierarchies

    Författare :Yoran Tournois; Maria Hermanns; Kareljan Schoutens; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fractional quantum hall effect; conformal field theory; Ginzburg-Landau-Chern-Simons; Chern-Simons; wave functions; anyons; fractional statistics; braiding; composite bosons; teoretisk fysik; Theoretical Physics;

    Sammanfattning : A core tenet of condensed matter physics has been that different phases of matter can be classified according to Landau's symmetry breaking paradigm. It has become clear, however, that phases of matter exist that are not distinguished by symmetry, but rather by topology. LÄS MER
