2. 1. Topology Meets Frustration : Exact Solutions for Topological Surface States on Geometrically Frustrated Lattices

   Author : Flore Kiki Kunst; Emil Bergholtz; Jack Lidmar; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Topology; boundary states; surface states; edge states; Chern insulator; Weyl semimetal; Theoretical Physics; teoretisk fysik;

   Abstract : One of the main features of topological phases is the presence of robust boundary states that are protected by a topological invariant. Famous examples of such states are the chiral edge states of a Chern insulator, the helical edge states of a two-dimensional Z2 insulator, and the Fermi arcs of Weyl semimetals. READ MORE

4. 2. Solvable Topological Boundaries

   Author : Flore Kiki Kunst; Emil Bergholtz; Henning Schomerus; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

   Abstract : The hallmark of topological phases of matter is the presence of robust boundary states. In this dissertation, a formalism is developed with which analytical solutions for these states can be straightforwardly obtained by making use of destructive interference, which is naturally present in a large family of lattice models.
