Rapidly-converging methods for the location of quantum critical points from finite-size data
M. Roncaglia, L. Campos Venuti, C. Degli Esposti Boschi
We analyze in detail, beyond the usual scaling hypothesis, the finite-size convergence of static quantities toward the thermodynamic limit. In this way we are able to obtain sequen…
Local Measures of Entanglement and Critical Exponents at Quantum Phase Transitions
L. Campos Venuti, C. Degli Esposti Boschi, G. Morandi +2
We discuss on general grounds some local indicators of entanglement, that have been proposed recently for the study and classification of quantum phase transitions. In particular,…
Analytic Relations between Localizable Entanglement and String Correlations in Spin Systems
L. Campos Venuti, M. Roncaglia
We study the relation between the recently defined localizable entanglement and generalized correlations in quantum spin systems. Differently from the current belief, the localizab…
