Factorization and criticality in the anisotropic XY chain via correlations
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 …

Quantum coherence and uncertainty in the anisotropic XY chain
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 …

Quantum discord in finite chains
L Ciliberti, R Rossignoli, N Canosa - … Review A—Atomic, Molecular, and Optical …, 2010 - APS
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 …

Strong monogamy conjecture for multiqubit entanglement: The four-qubit case
We investigate the distribution of bipartite and multipartite entanglement in multiqubit states.
In particular, we define a set of monogamy inequalities sharpening the conventional …

Finite-size scaling of coherence and steered coherence in the Lipkin-Meshkov-Glick model
Quantum coherence reflects the origin of quantumness and might be capable of extracting
the subtle nature of a system. We investigate the ground-state coherence and steered …

Genuine multipartite entanglement in a one-dimensional Bose-Hubbard model with frustrated hop**
S Singha Roy, L Carl, P Hauke - Physical Review B, 2022 - APS
Frustration and quantum entanglement are two exotic quantum properties in quantum many-
body systems. However, despite several efforts, an exact relationship between them remains …

Criticality, factorization, and long-range correlations in the anisotropic model
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 …

Average quantum coherence and its use in probing quantum phase transitions
XY Liu, ML Hu - Physica A: Statistical Mechanics and its Applications, 2023 - Elsevier
We investigate the average quantum coherence (AQC) defined to be the coherence of a
state averaged over all reference bases. This is a basis-independent measure and for any …
