    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Superconductivity; Odd-Frequency Superconductivity; Nematic superconductivity; Topological Phases of Matter; Flat bands; Van Hove Singularity; Graphene; Twisted Bilayer Graphene; Rhombohedral graphite; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : We explore the connection between robust material platforms for superconductivity and the modern condensed matter physics paradigms of two-dimensional materials, topological states of matter, and odd-frequency superconductivity. Specifically, the recent discoveries of gapless topological matter and truly two-dimensional materials with graphene have greatly expanded the class of materials for which topology produces large, robust, even singular, density of states (DOS) peaks in the electronic structure that in turn are highly susceptible to new ordered states of matter, including superconductivity.

  2. 2. Quasiparticles in the Quantum Hall Effect

    Författare :Janik Kailasvuori; Thors Hans Hansson; Jan Myrheim; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum Hall effect; quasiparticles; noncommutative Chern-Simons theory; nonabelian statistics; thin torus; p-wave superconductivity; topology; index theory; effective gauge fields; Condensed matter physics; Kondenserade materiens fysik;

    Sammanfattning : The fractional quantum Hall effect (FQHE), discovered in 1982 in a two-dimensional electron system, has generated a wealth of successful theory and new concepts in condensed matter physics, but is still not fully understood. The possibility of having nonabelian quasiparticle statistics has recently attracted attention on purely theoretical grounds but also because of its potential applications in topologically protected quantum computing.

  3. 3. Non-local behaviour from local interactions

    Författare :Thomas Kvorning; Thors Hans Hansson; Ady Stern; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Sammanfattning : With the discovery of the quantum Hall effect more than thirty years ago, a whole new field emerged—that of topological quantum matter. This field is now a very mature one, and many different aspects are covered in the literature. LÄS MER
