Reexamination of the purity entanglement measure: Peculiarities of a truly thermodynamic quantum correlation measure
The purity entanglement measure introduced by Los Alamos group a decade ago is reexamined in the light of interesting features. The role played by purity, reaching a real thermodynamic limit, in detecting quantum phase transitions is studied with a different system, the bond-alternating XY model in...
