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 $Z_{2}$ symmetry. For such models, the existence of a topologically ordered ground state has been proven…

Excitation gap of a blockade structure with $Z_{2}$ 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…
