We examine a class of bipartite mixed states which we call X states and report several
analytic results related to the occurrence of so-called entanglement sudden death (ESD) …

We study the entanglement dynamics of two qubits, each of which is embedded into its local
amplitude-damping reservoir, and the entanglement distribution among all the bipartite …

In a recent paper, it was shown that the projections of a relativistic spin operator (RSO)
massive spin-1 2 particle on a world-vector which can be in timelike or null tetrad direction …

It is shown that transient spin-spin correlations in a one-dimensional spin S≫ 1 chain can be
enhanced for initially factorized and individually squeezed spin states. Such correlation …

This thesis is a theoretical study of entanglement dynamics and its control of qubit-qubit and
qubit-qutrit systems. In particular, we focus on the decay of entanglement of quantum states …

By investigating the evolution of a moving spin-1 2 Dirac electron coupled with a
background magnetic noise, we demonstrate that the effects of special relativity will …

We have studied the stability of two entangled spins dressed by electrons by calculating the
scattering phase shifts. The interaction between electrons is interpreted by fully relativistic …

This paper is concerned with the spin–momentum correlation in single-particle quantum
states, which is described by the mixed states under Lorentz transformations. For …

We study the quantum correlation dynamics of bipartite spin-1 2 12 density matrices for two
particles under Wigner rotations induced by Lorentz transformations which is transmitted …

We investigate the Lorentz transformation of the reduced helicity density matrix for a pair of
massive spin 1/2 particles. The corresponding Wootters concurrence shows no invariant …
