  2. 1. Asymptotics of Eigenpolynomials of Exactly-Solvable Operators

    Author : Tanja Bergkvist; Boris Shapiro; Andrei Martinez-Finkelshtein; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; exactly-solvable; eigenpolynomials; zero distribution; asymptotics; MATHEMATICS; MATEMATIK; matematik; Mathematics;

    Abstract : The main topic of this doctoral thesis is asymptotic properties of zeros in polynomial families arising as eigenfunctions to exactly-solvable differential operators. The study was initially inspired by a number of striking results from computer experiments performed by G. Masson and B. Shapiro for a more restrictive class of operators. READ MORE

  4. 2. Bi2212 intrinsic Josephson junctions, fabrication and high frequency properties

    Author : Mattias Torstensson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; intrinsic Joule heating; Shapiro steps; in plane critical current; Bi2212; high temperature superconductors; intrinsic Josephson junctions;

    Abstract : The objective for this work was to investigate the high-frequency properties of Bi2212 intrinsic Josephson junctions (IJJ’s). Particularly, the possibility to reach the THz range with a SIS mixer is theoretically promising due to the high energy gap of Bi2212. READ MORE
