The entanglement at finite temperatures are analyzed by using thermal models for colored quarks making up the hadron physical states. We have found that these quantum correlations entirely vanish at ...\(T_c\geq m_q/\ln(1.5)\). For temperatures larger than \(T_c\) the correlations are classical. Also we worked out the entanglement for the transverse Ising spin chain. In dependence on both temperature \(T\) and transverse field \(\lambda\) we can identify a certain region, where the quantum effects are likely to dominate the system. We suggest the mutual information as a quantitative measure for the correlations in ground state.
We analyze the quantum entanglement at the equilibrium in a class of exactly
solvable one-dimensional spin models at finite temperatures and identify a
region where the quantum fluctuations determine ...the behavior of the system. We
probe the response of the system in this region by studying the spin dynamics
after projective measurement of one local spin which leads to the appearance of
the ``decoherence wave''. We investigate time-dependent spin correlation
functions, the entanglement dynamics, and the fidelity of the quantum
information transfer after the measurement.
Distillable entanglement (\(E_d\)) is one of the acceptable measures of entanglement of mixed states. Based on discrimination through local operation and classical communication, this paper gives ...\(E_d\) for two classes of orthogonal multipartite maximally entangled states.
We study the problem of optimization over positive valued-operator measure to
extract classical correlation in a bipartite quantum system. The proposed
method is applied to binary states only. ...Moreover, to illustrate this method,
an explicit example is studied in details.

Phys. Rev. A 67, 014301 (2003). In this paper we discuss the problem of splitting the total correlations for
a bipartite quantum state described by the Von Neumann mutual information into
classical ...and quantum parts. We propose a measure of the classical correlations
as the difference between the Von Neumann mutual information and the relative
entropy of entanglement. We compare this measure with different measures
proposed in the literature.
J.Phys.G27:427-438,2001 We identify the major physics milestones in the development of strange
hadrons as an observable for both the formation of quark-gluon plasma, and of
the ensuing explosive ...disintegration of deconfined matter fireball formed in
relativistic heavy ion collisions at 160--20A GeV. We describe the physical
properties of QGP phase and show agreement with the expectations based on an
analysis of hadron abundances. We than also demonstrate that the m_t shape of
hadron spectra is in qualitative agreement with the sudden breakup of a
supercooled QGP fireball.
