Topological and nematic ordered phases in many-body cluster-Ising models
S. M. Giampaolo, B. C. Hiesmayr
We present a fully analytically solvable family of models with many-body cluster interaction and Ising interaction. This family exhibits two phases, dubbed cluster and Ising phases…

Mutual information and spontaneous symmetry breaking
A. Hamma, S. M. Giampaolo, F. Illuminati
We show that the metastable, symmetry-breaking ground states of quantum many-body Hamiltonians have vanishing quantum mutual information between macroscopically separated regions,…

Global-to-local incompatibility, monogamy of entanglement, and ground-state dimerization: Theory and observability of quantum frustration in systems with competing interactions
S. M. Giampaolo, B. C. Hiesmayr, F. Illuminati
Frustration in quantum many body systems is quantified by the degree of incompatibility between the local and global orders associated, respectively, to the ground states of the lo…
