1. 1. A quantum for a quantum : Quantum simulators in exotic lattices

   Författare :Pil Maria Saugmann; Jonas Larson; André Eckardt; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum physics; condensed matter physics; quantum optics; optical lattices. Fock state lattices; exotic lattices; frustration; Theoretical Physics; teoretisk fysik;

   Sammanfattning : This thesis centers on how to use exotic lattices in different ways to design potential quantum simulators. These exotic lattices are either real physical objects in the form of ultra cold atoms in  bipartite optical lattice systems or lattice models revealed in state space. LÄS MER

3. 2. Solvable Topological Boundaries

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

   Sammanfattning : 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.

4. 3. Fermions in two dimensions and exactly solvable models

   Författare :Jonas de Woul; Edwin Langmann; Fabian Essler; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bosonization; Exactly solvable models; Hubbard model; Mean field theory; Quantum field theory; Strongly correlated systems;

   Sammanfattning : This Ph.D. thesis in mathematical physics concerns systems of interacting fermions with strong correlations. For these systems the physical properties can only be described in terms of the collective behavior of the fermions. LÄS MER
