Linear entropy fails to predict entanglement behavior in low-density fermionic systems

HIGHLIGHTS

• What: The authors investigate both linear and von Neumann entropies for quantifying entanglement in homogeneous superlattice and disordered Hubbard chains.
• Who: Posted Date March and colleagues from the Institute of Chemistry, São Paulo State University, Araraquara, São Paulo, Brazil have published the article: Linear entropy fails to predict entanglement behavior in low-density fermionic systems, in the Journal: (JOURNAL)

SUMMARY

Concerning entanglement measures, among the general class of Renyi entropies15, 16, the von Neumann17 is the most commonly used entropy for quantifying entanglement of bipartite pure states. Although the . . .
