    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transport; Knots; Topology; non-Hermiticity; Weyl semimetals; Theoretical Physics; teoretisk fysik;

    Abstract : Topology has manifestations in physics ranging from the field of condensed matter to photonics. This dissertation provides a two-fold study on the impact of topology in Hermitian and non-Hermitian band structures. READ MORE

  4. 2. Knotted Nodal Band Structures

    Author : Marcus Stålhammar; Emil Bergholtz; Edwin Langmann; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Abstract : It is well known that in conventional three dimensional (3D) Hermitian two band models, the intersections between the energy bands are generically given by points. The typical example are Weyl semimetals, where these singular points can be effectively described as Weyl fermions in the low energy regime. READ MORE
