Abstract:
In this study, spin squeezing was calculated for two common square systems in terms of the system variables using the Kitagawa parameter, and entanglement of these systems was compared based on the Meyer–Wallach and LE measures. Calculations showed a certain relationship between the Kitagawa parameter and the Meyer–Wallach measure in the two square systems. The correlation between squeezing and the Meyer–Wallach measure remains unchanged in cases where squeezing is dependent on the interaction between the sites. No correlation was found between entanglement in terms of the LE measure and squeezing in the studied systems. However, in one of the systems, a weak correlation between them was observed.
