Fracton and topological order in the XY checkerboard toric code
M. Vieweg, K. P. Schmidt
We introduce the XY checkerboard toric code. It represents a generalization of the toric code with two types of star operators with and flavor and two anisot…
Quantum-critical properties of the one- and two-dimensional random transverse-field Ising model from large-scale quantum Monte Carlo simulations
C. Krämer, J. A. Koziol, A. Langheld +2
We study the ferromagnetic transverse-field Ising model with quenched disorder at in one and two dimensions by means of stochastic series expansion quantum Monte Carlo simu…
Quantum robustness of the toric code in a parallel field on the honeycomb and triangular lattice
V. Kott, M. Mühlhauser, J. A. Koziol +1
We investigate the quantum robustness of the topological order in the toric code on the honeycomb lattice in the presence of a uniform parallel field. For a field in -direction,…
(Almost) Everything is a Dicke model -- Mapping non-superradiant correlated light-matter systems to the exactly solvable Dicke model
Andreas Schellenberger, Kai Phillip Schmidt
We investigate classes of interacting quantum spin systems in a single-mode cavity with a Dicke coupling, as a paradigmatic example of strongly correlated light-matter systems. Com…
Incorporating non-local anyonic statistics into a graph decomposition
M. Mühlhauser, V. Kott, K. P. Schmidt
In this work we describe how to systematically implement a full graph decomposition to set up a linked-cluster expansion for the topological phase of Kitaev's toric code in a field…
