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,…

Scaling of excitations in dimerized and frustrated spin-1/2 chains
D. Controzzi, C. Degli Esposti Boschi, F. Ortolani +1
We study the finite-size behavior of the low-lying excitations of spin-1/2 Heisenberg chains with dimerization and next-to-nearest neighbors interaction, J_2. The numerical analysi…
