Immobile and mobile excitations of three-spin interactions on the diamond chain

M. Bayer, M. Vieweg, K. P. Schmidt

We present a solvable one-dimensional spin-1/2 model on the diamond chain featuring three-spin interactions, which displays both, mobile excitations driving a second-order phase tr…

Absence of topological order in the $U (1)$ checkerboard toric code

M. Vieweg, V. Kott, L. Lenke +2

We investigate the $U (1)$ checkerboard toric code which corresponds to the $U (1)$ -symmetry enriched toric code with two distinct star sublattices. One can therefore tune from the l…

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 $Z_{2}$ toric code with two types of star operators with $x$ and $y$ flavor and two anisot…
