Topological symmetry breaking: Domain walls and partial instability of chiral edges
F. A. Bais, S. M. Haaker
In 2D topological systems chiral edges may exhibit a spectral change due to the formation of a Bose condensate and partial confinement in the bulk according to the topological symm…
Diagrammatics for Bose condensation in anyon theories
I. S. Eliëns, J. C. Romers, F. A. Bais
Phase transitions in anyon models in (2+1)-dimensions can be driven by condensation of bosonic particle sectors. We study such condensates in a diagrammatic language and explicitly…
Noncompact dynamical symmetry of a spin-orbit coupled oscillator
S. M. Haaker, F. A. Bais, K. Schoutens
We explain the finite as well as infinite degeneracy in the spectrum of a particular system of spin-1/2 fermions with spin-orbit coupling in three spatial dimensions. Starting from…
The modular S-matrix as order parameter for topological phase transitions
F. A. Bais, J. C. Romers
We study topological phase transitions in discrete gauge theories in two spatial dimensions induced by the formation of a Bose condensate. We analyse a general class of euclidean l…
Topological entanglement entropy relations for multi phase systems with interfaces
F. A. Bais, J. K. Slingerland
We study the change in topological entanglement entropy that occurs when a two-dimensional system in a topologically ordered phase undergoes a transition to another such phase due…
A theory of topological edges and domain walls
F. A. Bais, J. K. Slingerland, S. M. Haaker
We investigate domain walls between topologically ordered phases in two spatial dimensions and present a simple but general framework from which their degrees of freedom can be und…
