In this review, we discuss the zero and finite temperature behavior of various bipartite
quantum and total correlation measures, the skew information-based quantum coherence …

We explore the local quantum coherence and the local quantum uncertainty, based on
Wigner-Yanase skew information, in the ground state of the anisotropic spin-1/2 XY chain in …

We examine how effective-model-space (EMS) calculations of nuclear many-body systems
rearrange and converge multi-particle entanglement. The generalized Lipkin–Meshkov …

We examine the quantum discord between two spins in the exact ground state of finite spin-
1/2 arrays with anisotropic XY couplings in a transverse field B. It is shown that in the vicinity …

We investigate the existence and the properties of fully separable (fully factorized) ground
states in quantum spin systems. Exploiting techniques of quantum information and …

We study the long-range quantum correlations in the anisotropic XY model. By first
examining the thermodynamic limit, we show that employing the quantum discord as a figure …

We study the properties of multipartite quantum correlation (MQC) in a one-dimensional spin-
1/2 XY chain, where the three-spin reduced states are focused on and the four introduced …

The existence of definite orders in frustrated quantum systems is related rigorously to the
occurrence of fully factorized ground states below a threshold value of the frustration …

The ground state of a quantum spin chain is a natural playground for investigating
correlations. Nevertheless, not all correlations are genuinely of quantum nature. Here we …

We determine the conditions for the existence of a pair of degenerate parity breaking
separable eigenstates in general arrays of arbitrary spins connected through XYZ couplings …
