Fermionic many-body topology in cavity-coupled Su-Schrieffer-Heeger chains
Anna Ritz-Zwilling, Olesia Dmytruk
We study the effects of cavity-mediated interactions on the symmetries and topological properties of a Su-Schrieffer-Heeger chain coupled to a single mode photonic cavity. Consider…
Partition function of the Kitaev quantum double model
Anna Ritz-Zwilling, Benoît Douçot, Steven H. Simon +2
We compute the degeneracy of energy levels in the Kitaev quantum double model for any discrete group on any planar graph forming the skeleton of a closed orientable surface of…
Extended string-net models with all anyons at finite temperature
André O. Soares, Anna Ritz-Zwilling, Jean-Noël Fuchs
The string-net model describes a vast family of topological orders in two spatial dimensions. Here, we consider the effect of thermal fluctuations on these topological phases. In t…
Finite-temperature properties of string-net models
Anna Ritz-Zwilling, Jean-Noël Fuchs, Steven H. Simon +1
We consider a refined version of the string-net model which assigns a different energy cost to each plaquette excitation. Using recent exact calculations of the energy-level degene…
Effective models for dense vortex lattices in the Kitaev honeycomb model
David J. Alspaugh, Jean-Noël Fuchs, Anna Ritz-Zwilling +1
We introduce low-energy effective models for dense configurations of vortices in the Kitaev honeycomb model. Specifically, we consider configurations of vortices in which vortex-fr…
Topological and nontopological degeneracies in generalized string-net models
Anna Ritz-Zwilling, Jean-Noël Fuchs, Steven H. Simon +1
Generalized string-net models have been recently proposed in order to enlarge the set of possible topological quantum phases emerging from the original string-net construction. In…
Wegner-Wilson loops in string nets
A. Ritz-Zwilling, J. -N. Fuchs, J. Vidal
We study the Wegner-Wilson loops in the string-net model of Levin and Wen in the presence of a string tension. The latter is responsible for a phase transition from a topological d…
