Symmetry breaking and competing valence bond states in the star lattice Heisenberg antiferromagnet
Pratyay Ghosh, Jan Koziol, Samuel Nyckees +2
We investigate the ground state phase diagram of the spin- antiferromagnetic Heisenberg model on the star lattice using infinite projected entangled pair states (iPEPS) and hi…

Absence of topological order in the checkerboard toric code
M. Vieweg, V. Kott, L. Lenke +2
We investigate the checkerboard toric code which corresponds to the -symmetry enriched toric code with two distinct star sublattices. One can therefore tune from the l…
