Topological phase transition in a symmetric blockade structure
Johannes Mögerle, Simon Fell, Tobias F. Maier +4
We present a numerical study of a blockade Hamiltonian with a local symmetry. For such models, the existence of a topologically ordered ground state has been proven…

Excitation gap of a blockade structure with topological order
Simon Fell, Tobias F. Maier, Hans Peter Büchler +1
Mathematically rigorous statements on the spectral gap of quantum many-body systems in the thermodynamic limit are notoriously difficult to prove -- yet they are of fundamental imp…

Quantum doubles in symmetric blockade structures
Hans Peter Büchler, Tobias F. Maier, Simon Fell +1
Exactly solvable models of topologically ordered phases with non-abelian anyons typically require complicated many-body interactions which do not naturally appear in nature. This m…
