Quantum Correlations in One Parameter Mixed Quantum States

Munero et. al. developed one parameter family of mixed states ${\rho }^l$, which are more entangled than bipartite Werner state. The similar family of mixed states ${\rho }^n$ are developed by L. Derkacz et. al. with differed approach. Further the author extend ${\rho }^n$ to two parameter family of quantum states ${\rho }^m$ and characterized these states in terms of Bell inequality violation against their mixedness. In the present article, we investigate the comparative dynamics of all mixed states $({\rho }^l,{\rho }^n,{\rho }^m)$ under the bipartite Ising Hamiltonian exposed by the external magnetic field and investigate the dynamics of quantum correlations against the mixedness quantified by linear entropy
