MiS Preprint Repository

We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

Local quantum Fisher information and one-way quantum deficit in spin-$\frac{1}{2}$ $XX$ Heisenberg chain with three-spin interaction

Biao-Liang Ye, Bo Li, Xiao-Bin Liang and Shao-Ming Fei

Abstract

We explore quantum phase transitions in the spin-$\frac{1}{2}$ $XX$ chain with three-spin interaction in terms of local quantum Fisher information and one-way quantum deficit, together with the demonstration of quantum fluctuations. Analytical results are derived and analyzed in details.
